Technical Overview & Applications Use-case context
Sulfo-NHS-SS-Biotin, with a CAS number of 325143-98-4, is a cleavable biotinylation reagent used for labeling proteins and other molecules. It contains a sulfo-NHS ester group that reacts with primary amines to form stable amide bonds, allowing for efficient biotin labeling. The presence of a disulfide bond in the spacer arm enables the biotin label to be cleaved with reducing agents, such as dithiothreitol, making it a useful tool for applications where reversible biotinylation is required. This reagent is commonly used in various biochemical assays, including Western blotting, immunoprecipitation, and ELISA, to detect and analyze biotinylated proteins. Its water solubility and stability under physiological conditions make Sulfo-NHS-SS-Biotin a versatile and reliable choice for biotinylation reactions in a wide range of research applications.
