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.

Antibodies are immunoglobulins secreted by effector lymphoid B cells into the bloodstream. Antibodies consist of two light peptide chains and two heavy peptide chains that are linked to each other by disulfide bonds to form a “Y” shaped structure. Both tips of the “Y” structure contain binding sites for a specific antigen. Antibodies are commonly used in medical research, pharmacological research, laboratory research, and health and epidemiological research. They play an important role in hot research areas such as targeted drug development, in vitro diagnostic assays, characterization of signaling pathways, detection of protein expression levels, and identification of candidate biomarkers.
