Trypsin-ultra™, Mass Spectrometry Grade is a serine endopeptidase. It selectivelycleaves peptide bonds C-terminal to lysineand arginine residues (1). Trypsin-ultra istreated with L-(tosylamido-2-phenyl) ethylchloromethyl ketone (TPCK) to inactivate anyremaining chymotryptic activity. It is modifiedby acetylation of the ε-amino groups of lysineresidues to prevent autolysis. Trypsin-ultra (TPCKtreated)cleaves at Lys-Pro and Arg-Pro bondsat a much slower rate than other amino acidresidues (2).
Product Source
Isolated from bovine (Bos taurus) pancreas.
Reconstitution
Trypsin-ultra, Mass Spectrometry Grade should be reconstituted by the addition of 20–200 μl of high purity water. Rapid autolysis is a function of enzyme concentration.

DNase I 是一种核酸内切酶,降解双链或单链DNA,产生5-磷酸末端的单核苷酸及寡核苷酸,在Mg2+存在时,DNase I独立地作用每条DNA链,切割位点是随机分布,在Mn2+存在下,DNase I 作用于DNA双链的大致同一位置,产生钝末端或具1-2个核苷酸突起的DNA片段。来源:牛胰贮存条件:4℃应用:1、用切口平移法进行放射性标记时,可用DNase I在双链DNA上产生随机切口;2、在进行亚硫酸氢盐介导的诱变前,可用DNase... 查看更多>
