Description

Desthiobiotin-C2-CONH-PEG2-Iodoacetamide is used primarily in protein labeling, modification, and affinity purification applications in biochemical and biotechnological research. Its ability to selectively bind streptavidin or avidin and modify cysteine residues in proteins makes it valuable in various experimental techniques aimed at studying protein function, interactions, and localization within biological systems. Desthiobiotin binds avidin and streptavidin proteins with high affinity, similar to biotin, but with lower binding strength, making it useful for reversible binding applications. Iodoacetamide is a chemical compound used to modify cysteine residues in proteins through alkylation. It forms stable thioether bonds with cysteine sulfhydryl groups, facilitating covalent attachment of the compound to proteins.
