Description

Biotin-PEG2-alkyne is a compound consisting of a biotin molecule attached to a PEG chain, which is further functionalized with an alkyne group. Biotin is a small molecule that forms a strong, non-covalent interaction with avidin, streptavidin, or neutravidin proteins. This interaction is widely used in various biological assays and techniques, including protein purification, immunoprecipitation, and detection. Alkynes are commonly used in click chemistry reactions, particularly the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, for the selective and efficient conjugation of biomolecules. This compound can be used to biotinylate biomolecules such as proteins, peptides, nucleic acids, or small molecules. The biotin moiety allows for specific binding to streptavidin or avidin, enabling downstream applications such as protein purification, detection, or immobilization. Additionally, it is useful for protein labeling and detection assays. By conjugating the compound to proteins of interest and subsequently binding them to streptavidin or avidin-coated surfaces, researchers can detect and quantify protein levels in complex biological samples.
