Description

Biotin-PEG4-C1-alkyne is a molecule designed for bioconjugation applications, particularly in the context of attaching biotin to other molecules or surfaces using click chemistry. The C1-alkyne group (-C≡CH) is an alkyne functional group that serves as a bioorthogonal handle. It reacts specifically and efficiently with azide groups via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or “click chemistry”. This reaction is highly selective, proceeds under mild conditions (typically in aqueous solutions), and forms stable triazole linkages. Biotin, also known as vitamin B7, is a small molecule that binds tightly to avidin or streptavidin proteins. PEG spacers are hydrophilic and flexible, designed to increase solubility, reduce steric hindrance, and improve the accessibility of biotin for interactions with other molecules.
