Deoxynucleotide (dNTP) Solution Mix as an equimolar solution of ultrapure, HPLC purified (>99%) dATP, dCTP, dGTP and dTTP for qPCR, RT-PCR, standard PCR, and Klenow reactions. The Genaxxon dNTP solutions are optimized for use in DNA amplification and other related methods. The Genaxxon dNTPs and dNTP-mixes contain no measurable bacterial or human DNA. For long term storage and/or for repeated use we do recommend to aliquot the stock solutions. Mixture of dNTP sodium salts (dATP, dCTP, dGTP und dTTP) Concentration: 10 mM each nucleotide Please have also a look on our broad range of nucleotides especially the dNTP mix withv2 mM dNTP mix , our dNTP set, or modified nucleotides, e.g. Biotin-11-dUTP. You can get additional products for your successful PCR as our Taq DNA Polymerse (M3001), or our proof-reading polymerases Pfu (M3004), Pwo (M3002) and ReproFast (M3003), as well as the ready-to-use RedMastermix (M3029), already including dNTPs.

Overview:Proteinase K is a robust and versatile serine protease used extensively in molecular biology for the digestion of proteins in nucleic acid preparations. This solution, at a concentration of 20 mg/mL, is ideal for a wide range of applications including the preparation of DNA and RNA samples. The PCR grade quality ensures that the enzyme is free from contaminants that could interfere with downstream applications, making it highly suitable for sensitive techniques such as PCR.Product Details:ready-to-useConcentration: 20 mg/mLactive over a wide range of reaction conditionsAn elevation of the reaction temperature from 37°C to 50 - 60°C may increase the activity several timesQuality: PCR grade, ensuring high purity and no interference with PCR reactions.Applications: Suitable for DNA and RNA extractionRemoval of protein contaminantsPreparation of samples for various molecular biology techniques.Benefits:High Purity: The PCR grade quality guarantees minimal contamination, ensuring reliable results in sensitive applications. Versatility: Ideal for various molecular biology procedures, including sample preparation for PCR.Convenience: Ready-to-use solution at an optimal concentration for ease of use. Notes:The recommended working concentration of Proteinase K is 0.05 to 1 mg/mL. The activity of the enzyme is stimulated by 0.2 to 1% SDS and also by 1 to 4M ureaCa2+ protects Proteinase K against autolysis and increases the thermal stabilityStable over a wide pH range: 4.0 to 12.5, optimum pH 7.5 to 8.0Activity optimum: 50°C to 55°CRapid denaturation of enzyme occurs at temperatures above 65°CFeatures:No detected exonuclease, endonuclease or RNase activitySpecific activity: >40 units/mg protein Activity: ≥30 units/mg lyophilizateSolubility: ≥20 mg/mLDNA content ≤10 pg/mgShipping conditions: Shipment on wet iceInhibitors of proteinase KWhich substances can inhibit proteinase K? Proteinase K can be inhibited by a variety of substances. These include ‘denaturing substances’, detergents and proteinase inhibitors. Sensitivity to inhibitors depends pretty much on the specific application (exact pH, concentration, temperature). Inhibitors frequently used in biochemistry and molecular biology are:SDS: High concentrations of SDS can denature and inactivate proteinase K.EDTA: EDTA is a chelating agent that can bind to metal ions that are essential for proteinase K activity.Urea: High concentrations of urea can denature and thereby inactivate proteinase K.Detergents: Some detergents, such as Triton X-100 or Tween® 20, can inhibit proteinase K, especially when the detergents are present in high concentrations.Protease inhibitors: Protease inhibitors, such as phenylmethylsulfonyl fluoride (PMSF), can irreversibly inhibit proteinase K.Chaotropic salts: Depending on the DNA extraction protocol, the presence of chaotropic salts or detergents may increase proteinase K activity. However, the same reagents may also inhibit proteinase K activity.Proteinase K can be obtained from Genaxxon as Powder (M3036) > or as 20mg/mL Solution (M3037) >.Produced by Genaxxon bioscience GmbH, founded in 2002 by Dr. Norbert Tröndle to provide reliable products for PCR and custom cell culture media formulations, the Proteinase K Solution 20 mg/mL offers a dependable and efficient solution for your molecular biology needs. Achieve consistent, high-quality results with an enzyme designed specifically for your requirements.

SafeGel red stain is an ultra sensitive, extremely stable fluorescent dye designed to replace the toxic and possibly mutagenic ethidium bromide (EtBr) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels. SafeGel red stain is far more sensitive than EtBr without requiring a destaining step. SafeGel red stain is far less toxic and mutagenic compared to EtBr while both show virtually the same UV-spectra, so you can directly replace EtBr with SafeGel red stain without changing your existing imaging system. SafeGel can be used to stain dsDNA, ssDNA or RNA in agarose gel via either precast or post gel staining. SafeGel can also be used to stain dsDNA, ssDNA or RNA in polyacrylamide gel via post gel staining. SafeGel is also compatible with downstream DNA manipulations such as digestion with a restriction enzyme, Southern blotting techniques and clonings. A series of safety tests has confirmed that SafeGel is noncytotoxic, nonmutagenic and nonhazardous even at concentrations above the working concentrations used in gel staining. As a result, SafeGel can be safely disposed in regular trash, providing convenience and reducing cost in waste disposal. This fluorescent dye is supplied as a 10,000X solution in water. For customers who look for large pack size, we offer a cost-saving bulk pack size of 2mL, 5mL or 10mL (M3193.1010). Read in our blog why you should use Genaxxon's SafeGel now. For high-class agarose gels we offer the Genaxxon standard agarose LE > or our speciality agaroses for high resolution Tiny (M3046) > and Tiny HT (M3047) >.
