BiotinylationKit Peptide biotinylation is a cornerstone technique in molecular biology and biochemistry, offering a powerful method for selectively labeling, detecting, and manipulating peptides and other biomolecules. This process, also known as biotin labeling, involves the covalent attachment of biotin to a molecule of interest. The resulting biotinylated peptides possess a unique affinity for avidin and streptavidin, proteins that bind biotin with exceptionally high affinity, forming the basis for a wide array of research and diagnostic applications.

The fundamental principle behind peptide biotinylation lies in the strong, specific interaction between biotin and avidin/streptavidin. This interaction, with an association constant of approximately 10^15 M^-1, is one of the strongest known non-covalent biological interactions.作者：S Renuse·2020·被引用次数：25—Biotinylation of proteins is an often-used molecular handlethat allows for robust purification of proteins.
