What is Biotin-PEG3-NHS ester?
Description
Biotin-PEG3-NHS ester is an biotinylation compound that can couple with primary amino groups (-NH2). The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds.
General Description
Biotin-PEG3-NHS ester is useful for biotinylation of proteins with free primary amine groups. It is an biotinylation compound that can couple with primary amino groups (-NH2). The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds.
General Description
Biotinylation reagent with N-hydroxysuccinimide ester, and a 3 PEG spacer. The NHS group reacts with the e-amino group on lysines, the N-terminus of proteins, and other primary amines.
Storage
Store at or below ≤4°C. Solid form is stable at least 2 years from date of receipt, when stored as directed.
