Ceramic beads for the lysis of tissue from a wide range of sample material, e.g. for RNA extraction. The kit contains 100 preps with 1.4mm ceramic beads (zirconia) and comes pre-proportioned to 1g in 2mL standard screw cap tubes. The beads are suitable for the homogenization of "soft" tissue from lung, liver, brain, kidney, spleen, skin, cells from cell culture, as well as for plant tissues such as e.g. Leaves or even whole insects. The usabl sample amount ranges from up to 200mg tissue, up to 200μL of cells suspended in water or isotonic saline solution, or up to 100mg wet weight of tissue culture cells grown in suspension (e.g., ≤107 mammalian cells). The beads can be used for a variety of samples and applications, e.g. B. for veterinary diagnostics (BSE screening), pharmacology and toxicology (drug detection), criminology and forensic medicine, food industry (GMO detection), microbiology in the environment (microorganism lysis). as well as the isolation of nucleic acids and proteins. They are chemically inert and do not bind nucleic acids. The beads are comparable with MP Biomedical No. 116913100 (equivalent to Lysing Matrix D) and are compatible with most commercially available homogenizers, like FastPrep® (MP Biomedicals), MagNA Lyser Instrument (Roche).

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.
