Biotin-PEG4-S-S-NHS Chemical Properties,Usage,Production

Description

Biotin-PEG4-S-S-NHS is a cleavable reagent useful for introducing a biotin moiety to proteins and cell surfaces containing primary amines. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP to remove the biotin label.

Uses

NHS-SS-dPEG4-biotin (cleavable) is a biodegradable crosslinker with efficient bioconjugation activity. NHS-SS-dPEG4-biotin (cleavable) can effectively connect biomolecules, optimize the efficiency of biolabeling, and be used in targeted compound delivery systems. NHS-SS-dPEG4-biotin (cleavable) can also play an important role in protein engineering and fluorescence imaging.

reaction suitability

reaction type: Biotinylations
reagent type: cross-linking reagent
