TS biotin ethylenediamine (Biotin-X ethylenediamine thiosulfate, sodium salt) is a highly selective thiol labeling probe. Similar to the MTS group, TS (thiosulfate) group is capable of reacting with thiols at nearly neutral pH. However, unlike the MTS group , which is neutral, TS is negatively charged and thus probes bearing a TS group are ideal for specifically labeling thiols exposed at the exterior cell surface because charged probes are less likely to enter cells. The X spacer should facilitate the interaction between biotin and avidin or streptavidin.Off-white liquid soluble in DMSO or water Store desiccated at -20°C C20H34N5NaO7S3 MW: 575.70
