Biotin-PEG2-NH-Boc(CAT: I014192) is a biotin PEG linker. This compound consists of a biotin group, a PEG chain, and a Boc-protected amino group. Biotin-PEG2-NH-Boc is commonly used in the field of bioconjugation and drug development, particularly in the creation of antibody-drug conjugates (ADCs). The biotin group allows for specific binding to avidin or streptavidin, enabling targeted delivery of the conjugate to biotin-binding proteins or cells. The PEG chain provides flexibility and solubility, and the Boc protection can be removed to expose the amino group to further chemical reactions.
