PEG

Biotinylation reagent that binds the C-terminus of peptides and carboxylic acid groups on aspartate or glutamate residues. Contains a very long (11 PEG) spacer arm. Requires a crosslinker such as EDC.

Biotinylation reagent with N-hydroxysuccinimide ester, and a 4 PEG spacer. The NHS group reacts with primary amines at pH 7.0-9.0. Can be used to label the e-amino group on lysines, the N-terminus of proteins, and other primary amines.

Biotinylation reagent with short 2 PEG spacer. Has a carboxyl group with a free -OH that can react with activated surfaces or can be converted to another reactive functionality.

Biotinylation reagent with short 2 PEG spacer. Has a carboxyl group with a free -OH that can react with activated surfaces or can be converted to another reactive functionality.

Biotinylation reagent with 3 PEG spacer. Has a carboxyl group with a free -OH that can react with activated surfaces or can be converted to another reactive functionality.
