SH-PEG-Biotin is a PEG derivative bound to avidin or streptavidin, which is mostly used on the surface of biomolecules or other materials. SH-PEG-Biotin is used for PEGylation through high affinity and specific binding chain mycoavidin or avidin.

SH-PEG-Biotin can easily detect biotin through the biotin/streptavidin binding assay, so it is widely used in molecular target detection.

Biopharma PEG provides high purity PEG derivatives with an extensive variety of functional groups(such as SH-PEG-Biotin), from grams to kilogram, even tons batch size in both non-GMP and GMP grades. Email at [email protected] and start using a superior product for your next product R&D project.
