s tag peptide

S Tag Peptide, a 15-amino acid peptide, is derived from RNase A.

S Tag Peptide acetate 是源自胰核糖核酸酶 A 的短肽片段，可由 pCITE-3/-4 系列载体用于体外翻译，或由 pET-29/-30 载体在 E. coli 中表达。该肽常融合于目标蛋白 N 端，包含三种阅读框均可使用的多克隆位点区域，便于高效的蛋白表达、纯化及功能研究。

X-press Tag is an N-terminal leader peptide; this N-terminal peptide contains a polyhistidine sequence, the Xpress epitope (part of bacteriophage T7 gene 10 protein) and an enterokinase cleavage site. Anti-Xpress antibodies recognize the Xpress epitope se
