Biotin-PEG-Mal (Biotin-PEG-Maleimide) is a bifunctional PEG reagent with a biotin group at one end and a maleimide group at the other. The biotin group serves as an affinity label for proteins such as avidin and streptavidin, enabling targeted binding with high specificity and affinity. The maleimide group reacts with thiol groups on cysteine residues or other thiol-containing molecules through Michael addition, forming stable thioether bonds. This reagent is commonly used in bioconjugation, protein labeling, and the development of targeted drug delivery systems due to its versatile functional groups and enhanced solubility provided by the PEG spacer.

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.
