GENAzol is a ready-to-use reagent for the isolation of high-quality total RNA or the simultaneous isolation of RNA, DNA and proteins from biological samples. With this single phase solution of phenol and guanidine isothiocyanate, RNA, DNA and proteins in different fractions from cell and tissue samples, e.g. isolated from humans, animals, plants, yeasts, bacteria or viruses (usually within an hour). This is a dangerous good with UN number UN2821. Not for sale outside the European Union. Properties of GENAzol:- Parallel isolation of RNA, DNA and protein from the same sample- Superior suitability for lysis even with difficult samples- Optimized formulations and protocols for tissues, cells, blood, viruses and bacteria. Reliable purification of RNA from samples of different volumes and sourcesGENAzol is also suitable for small amounts of tissue (50–100mg) and cells (5× 10E6) as well as for larger amounts of cells (>10E7) and contains protocols for the purification of RNA from human, animal, plant or bacterial Rehearse. GENAzol maintains the integrity of the RNA due to the very effective inhibition of RNase activity when cells and components are dissolved during sample homogenization. GENAzol enables the simultaneous processing of a large number of samples. The entire isolation step is usually completed in 1 hour. The total RNA isolated with GENAzol is free from protein and DNA contamination. Procedure for the isolation of RNA, DNA and proteinsGENAzol enables sequential precipitation of RNA, DNA and proteins from a single sample. After homogenizing the sample with GENAzol, chloroform is added and the homogenate separates into a clear aqueous top layer (which contains RNA), a boundary layer and a organic bottom layer (with DNA and proteins). RNA is precipitated from the aqueous layer with isopropanol. DNA precipitation from the organic boundary layer takes place with ethanol. Finally, the protein from the phenol-ethanol supernatant is precipitated with isopropanol. Precipitated RNA, DNA or protein is washed to remove impurities and then resuspended for use in subsequent applications.

Protein purification based on magnetic beads has become popular because they are useful to extract proteins from diluted solutions, such as cell culture supernatants purify proteins expressed at low levels perform pull-down experiments We use magnetic beads with a ferrimagnetic core and an agarose coating coupled to a ligand of choice, our beads meet our own high quality standards. They enable fast and easy purification steps, which can be automated. The amount of magnetic beads used for a purification setup can be easily scaled up and down to match protein expression rates and culture volumes. Genaxxon MagBeads are ferrimagnetic agarose beads coupled to a chelating ligand (IDA or NTA) coordinating nickel or cobalt ions. All offered ligand-metal systems efficiently bind histidine-tagged proteins. With a binding capacity of up to 40mg protein per mL (Ni-IDA) and 70mg per mL (Ni-NTA) of settled MagBeads, Genaxxon Ni-IDA MagBeads are comparable to equivalent beads from alternative providers.

NTA-Agarose consists of the tetradentate chelating agent, nitrilotriacetic acid (NTA), covalently coupled agarose beads, and is loaded with Co2+ ions. In processing recombinant fusion proteins from eukaryotes or in the case of special protein complexes, Genaxxon Co-NTA Agarose should always be used offering the possibility of higher protein purity levels. Both metal ions feature differing spatial properties and electronic binding potentials. While Co2+ binds only domains adjacent to residual histidine and is thus highly selective for 6×histidine-tagged fusion proteins, Ni2+ ions are less specific and can bind residual histidine outside the polyhistidine tag, which may result in higher contamination with foreign proteins. The unique production process yields a Co-NTA Agarose that exhibits a higher protein binding capacity than that of leading competitor products. Genaxxon Co-NTA Agarose is very robust in the presence of DTT and EDTA. In a stability test, Genaxxon Co-NTA Agarose was exposed to increasing concentrations of DTT or EDTA for 1h. Thereafter, the resins were used to purify E. coli-expressed GFP-His in gravity columns. The binding capacity of the resin decreased in the presence of both DTT and EDTA but the decay rate was shallow. Genaxxon NTA Agarose is supplied as a 50% buffered suspension in 20% Ethanol.

Nickel-loaded agaroses are the most frequently used products for the efficient purification of 6×histidine-tagged recombinant fusion proteins. Because Ni2+ ions show high affinity for 6×histidine-tagged fusion proteins, extremely high yields result from purification of these fusion proteins from the lysates. However, if purification takes place from lysates containing foreign protein chains with repeated histidine elements, selectivity with respect to 6×histidine-tagged fusion protein decreases as non-tagged histidine-containing proteins increasingly also bind to the Ni-IDA agarose. In this case the use of Genaxxon Co-IDA Agarose is recommend (cat#: S5370), which features far higher selectivity with respect to 6×histidine-tagged fusion protein. Genaxxon Ni-IDA Agarose has high chemically and pH stability and enables purification directly from raw lysates. Genaxxon Ni-IDA Agarose can be regenerated several times with nickel sulfate solution for re-use.

Genaxxon´s Total RNA Purification Kit - Tissue is designed for the rapid and efficient purification of high quality RNA from 1-30mg of tissue (fresh or frozen) or up to 25mg Paraffin embedded tissue. The isolation protocol and buffer formulations were optimised for high isolation efficiency and purity of RNA. The Total RNA Purification Kit utilises spin columns with membranes which efficiently and selectively bind nucleic acids at high concentration of chaotropic salts. The isolation procedure consists of 6 steps. In the first isolation step, the tissue is homogenized in order to disintegrate intercellular bonds (epithelial tissue) and fragmentize high-molecular proteins (muscle or connective tissue). Then the homogenate is lysed. Any RNases are inactivated. The three-step washing stage effectively removes impurities and enzyme inhibitors. The purified RNA is eluted using a low ionic strength buffer or RNase-free water and can be used directly in all downstream applications such as RT-PCR, Northern blotting, RT-qPCR and so forth. Genaxxon offers also ceramic beads > for rapid cell disintegration and other RNA purification kits >.

Protein purification based on magnetic beads has become popular because they are useful to extract proteins from diluted solutions, such as cell culture supernatants purify proteins expressed at low levels perform pull-down experiments We use magnetic beads with a ferrimagnetic core and an agarose coating coupled to a ligand of choice, our beads meet our own high quality standards. They enable fast and easy purification steps, which can be automated. The amount of magnetic beads used for a purification setup can be easily scaled up and down to match protein expression rates and culture volumes. The rho1D4 purification system is based on the highly specific binding of the rho1D4 antibody to the rho1D4 epitope fused to proteins. This system has proven particularly effective with membrane proteins. Magnetic beads are useful for protein purification of dilute samples, and for pull-down experiments to determine protein-protein interactions. Elution of the protein can be done the rho1D4 peptide, which competitively binds to the rho1D4 antibody, thereby release the traget protein. The peptide can be purchased individually, or together with Genaxxon Rho1D4 MagBeads as part of a Starter Set. A 5% suspension is provided that binds up to 3mg of protein per mL settled beads. Human rhodopsin is a G-protein coupled receptor and an integral membrane protein of the light-absorbing molecules that mediate vision. It consists of a protein, opsin, which is covalently bound to 11-cis-retinal. Rhodopsin expression has been reported in rod-shaped photoreceptor cells of the retina. Retinitis pigmentosa is a hereditary disease of photoreceptor degeneration. Phosphorylation of rhodopsin at multiple phosphorylation sites is required for its rapid and reproducible deactivation.

Glutathione MagBeads are developed for the affinity purification of glutathione-S-transferase (GST) fusion proteins. The affinity matrix is based on spherical magnetic cross-linked agarose. The material is highly porous to allow optimal protein interaction. Cross-linked agarose is also physically very stable, making it suitable for purification processes without deformation or destruction. Our magnetic beads are very homogeneous in size with a medium particle diameter of 30µm, yielding a high degree of reproducibility between individual purification runs.Glutathione is coupled to the magnetic agarose beads to obtain an affinity matrix with highest binding capacity for GST fusion proteins. Because the purification method depends on correctly folded GST protein, only native conditions can be used.Glutathione MagBeads are delivered as a 25% suspension in 20% ethanol. Therefore, 1mL suspension will yield a 250µL bed volume. The suspension contains 20% ethanol to prevent microbial growth. Genaxxon MagBeads have a binding capacity of >10mg protein/mL settled beads. Protein Binding CapacityThe protein binding capacity is up to 10mg/mL settled beads, as determined by purification of glutathione-S-transferase (GST) from E.coli cleared lysates, and quantified via spectrophotometry. GST-tagged proteins expressed in bacteria, yeasts, insects and in cell culture supernatants can be readily purified in a single purification step even from proteins expressed at low levels. After binding of target molecules, the magnetic resin can be readily isolated with the aid of a magnet. The GST tag can be cleaved in bound condition or in eluted condition by specific proteases such as TEV-express. The amount of magnetic beads used for a purification setup can be easily scaled up and down to match protein expression rates and culture volumes. Genaxxon MagBeads are ferrimagnetic agarose beads coupled to glutathione, an efficient ligand for GST fusion proteins. Human rhodopsin is a G-protein coupled receptor and an integral membrane protein of the light-absorbing molecules that mediate vision. It consists of a protein, opsin, which is covalently bound to 11-cis-retinal. Rhodopsin expression has been reported in rod-shaped photoreceptor cells of the retina. Retinitis pigmentosa is a hereditary disease of photoreceptor degeneration. Phosphorylation of rhodopsin at multiple phosphorylation sites is required for its rapid and reproducible deactivation.

The GST tag is a 26 kDa protein that binds to glutathione-coupled agarose resins. This tag is considerably larger than the His tag and is often chosen to promote recombinant protein folding. In a comparative study with equivalent, market-leading resins, Geanxxon's Glutathione Agarose proved to be a competitive alternative, exhibiting the same protein binding capacity. Compared to competitor G both resins yielded up to 10mg/mL protein. Protein binding capacity: up to 10mg/mL. Compatible with a range of detergents and additives.

The Medicago Protein L-Ligand Leakage Elisa kit has been designed to detect and quantify Protein L in Immunoglobulin (Ig) or Ig-fragment containing solutions, e.g. eluates from Protein L affinity chromatography. The kit was developed as a complement to Cytiva’s affinity chromatography medium Capto L.Easy, stepwise procedureThe Protein L Ligand Leakage Elisa kit is easy to use. It contains all the components necessary for your daily lab routine and is based on a simple stepwise procedure. The concentration of Protein L in your samples is calculated and presented as a calibration curve indicating any ligand leakage in your eluates.Verification of pharmaceutical processesThe kit is for verifying affinity chromatography process quality in purification of pharmaceuticals using chromatography. A low leakage level of Protein L in the column used is proof that both the medium and the process as such are performing as expected. Compared to developing your own protocols, using this validated detection kit is an easy and secure way for researchers and manufacturers to continuously check for leakage and to ensure process quality.The kit comes as a sandwich ELISA with microtiter strips coated with an affinity purified anti-Protein L IgY-antibody. In this assay, samples are boiled to separate the Ig/Ig-fragments from the Protein L in the solution, centrifuged, and incubated in the strip wells. The bound Protein L is then detected by adding a horseradish peroxidase (HRP)-conjugated anti-Protein L IgY antibody. Substrate is added to induce a color change which is proportional to the amount of bound Protein L from the sample. The color change is quantified spectrophotometrically at 450nm by using a plate reader. The amount of Protein L in the sample is determined by using a standard curve prepared in a reference sample. The reference sample should have the same concentration of Ig or Ig-fragments and preferably the same buffer composition as the elution samples from the Protein L affinity chromatography medium. However, it should be prepared using another purification strategy, e.g. ion exchange chromatography. Once a reference sample is created it can be aliquoted and used for several different protein L ELISA assays. ApplicationsDetermination of leakage levels of Protein L in Protein L-medium purification of intact immunoglobulin or immunoglobulin fragments (Ig or Ig fragments). Some fab samples may require optimization. Currently there is no protocol available for sdab molecules. Shipping and storageThe product is shipped cooled (+2°C to +8°C) except the Protein L reference which is shipped frozen (-20°C). On arrival store components cooled ( +2°C to +8°C ) except the Protein L reference which should be stored at -20/-80°C.Strips (96 wells): Store unused strips in sealed bag at +2°C to +8°C . HRP-conjugated anti Protein L pAb and EC-Blue Enhanced TMB-substrate: Store protected from light. Protein L reference: Store in working aliquots to avoid repeated freezing/thawing.
