Biotin-PEG4-S-S-NHS is commonly used for labeling proteins or peptides. The NHS ester group reacts with primary amines on proteins to form stable amide bonds. This labeled protein can then be used in various biochemical assays, such as ELISA, Western blotting, or immunoprecipitation, where detection or purification via streptavidin/biotin interaction is required. The S-S linkage refers to a disulfide bond (-S-S-) which is a cleavable bond under reducing conditions, typically involving thiols (-SH). This disulfide linkage allows for reversible conjugation or release of biotinylated molecules under appropriate conditions.
