AmpErase® Uracil N-glycosylase (UNG)

Category: Products & Services > Proteins, Enzymes, & Peptides > Enzymes > DNA⁄RNA Modifying Enzymes

Applied Biosystem® AmpErase® Uracil N-glycosylase (UNG), part of the GeneAmp® PCR Carry-over Prevention Kit, is a 26 kDa ultrapure, recombinant enzyme encoded by the E. coli uracil N-glycosylase gene, which has been inserted into an E. coli host to direct the expression of the wild type form of the enzyme. The GeneAmp® PCR Carry-over Prevention Kit provides reagents for a simple yet powerful method of ensuring that PCR products cannot be reamplified in subsequent PCR amplifications, thereby preventing false positive results. • Enzymatic method stops PCR carryover contamination, which prevents ...

RNase Cocktail™ (1 ml Tube)

Category: Products & Services > Proteins, Enzymes, & Peptides > Enzymes > DNA⁄RNA Modifying Enzymes

Ambion® RNase Cocktail™ is a mixture of two highly purified ribonucleases, RNase A (500 U/mL) and RNase T1 (20,000 U/mL), and is free of DNase and nicking activities. Use RNase Cocktail™ for all situations where it is desirable to degrade RNA, i.e. plasmid minipreps and ribonuclease protection assays. Supplied in five tubes containing 1 mL each. Digestion of RNA with RNase A alone leaves fragments of RNA that are large enough to be visible on agarose gels and precipitate in ethanol. RNase A cuts after C and U residues, and RNase T1 cuts after G residues. Consequently, the mixture of both enzym...
