Sulfo-NHS-LC-Biotin is a labeling reagent with a long-chain structure that reacts with amines. Its biotin-like groups can be efficiently eluted from streptomycin avidin, making it suitable for purification or labeling of cell surface proteins. The spacer arm between the biotin and amine reactive linker is large, aiding in overcoming steric hindrance and enhancing the efficiency of surface labeling [1-3].
Sulfo-NHS-LC-Biotin (10 mM) can be used for biotinization of exosomes from Mycobacterium tuberculosis (Mtb)-infected cells [4]. Sulfo-NHS-LC-Biotin also can be used for label cells[5]. It also can monitor sertoli cell Blood-Testis Barrier (BTB) integrity [6].
