Biotin-PEG2-Mal (Cat No.:I014191) is a compound commonly used in bioconjugation and protein labeling applications. It consists of three components: biotin, a polyethylene glycol (PEG) spacer, and a maleimide functional group. The biotin portion enables specific binding to avidin or streptavidin, facilitating the attachment of biotinylated molecules to surfaces or proteins. The PEG spacer provides flexibility and distance between the biotin and the maleimide group. The maleimide group selectively reacts with thiol-containing compounds, allowing for efficient conjugation. Biotin-PEG2-Mal is widely utilized in biochemical and biotechnological research for various labeling and conjugation purposes.
