Description

(+)-Biotin-PEG4-CH2CH2NH2 combines the specificity of biotin for streptavidin with the advantages of PEGylation and a flexible aminoethyl linker. Biotin is well-known for its strong binding affinity to streptavidin, a protein derived from Streptomyces avidinii. This interaction is utilized in various biological assays and techniques such as ELISA (enzyme-linked immunosorbent assay), immunohistochemistry, and affinity purification. The PEG4 spacer in (+)-Biotin-PEG4-CH2CH2NH2 can provide flexibility and accessibility to biotin, potentially enhancing its binding efficiency to streptavidin.
