Biotin-PEG-COOH

Supplementary Information:
Synonyms： Biotin-PEG-Acid Purity： ≥95% Recommended Storage Condition： Store at -5°C,keep in dry and avoid sunlight. Uses： Applicated in medical research, drug-release, nanotechnology and new materials research, cell culture. In the study of ligand, polypeptide synthesis support, a graft polymer compounds, new materials, and polyethylene glycol-modified functional coatings and other aspects of the active compound. BIOTIN-PEG-COOH is a linear heterobifunctional PEG with biotin and carboxylic acid functional groups. Biotin can bind to avidin and streptavidin with high specificity and affinity and realize non-covalent pegylation. BIOTIN-PEG-COOH can simply and effectively biotin-label antibodies, proteins and any other macromolecules containing primary amines in the presence of condensing agents.
