Catalog No. : PBL-8062
Product Name : HS-PEG-NH2, MW 2k
Description :

HS-PEG-NH2 is a linear heterobifunctional PEGylation reagent with a thiol and an amine. It is a useful crosslinking or bioconjugation reagent with a PEG spacer. Thiol, or SH, sulfhydryl, or mercapto group selectively reacts with maleimide, OPSS, vinylsulfone and transition metal surface including gold, silver, etc.
