Description

Biotin-PEG3-amido-Mal (Mal-Amido-PEG3-Biotin) is a compound which is used for protein labeling, affinity purification, surface modification, and immunoassays. The biotin moiety offers extremely strong and specific binding to streptavidin and avidin, which is utilized in various purification and detection methods. The maleimide group reacts specifically with thiol groups, enabling targeted labeling and conjugation to cysteine residues in proteins and other thiol-containing molecules. The PEG spacer improves the solubility of the reagent in aqueous solutions and reduces steric hindrance, enhancing the efficiency of bioconjugation reactions.
