Protein Labeling Reagents
Biotium MTSEA Biotin
MTSEA biotin selectively labels thiols under mild conditions. We offer MTSEA biotin with different linker lengths (Biotin-MTSEA, Biotin-X-MTSEA, and Biotin-XX-MTSEA), all of which allow selective labeling of cell surface thiols. Longer linkers should facilitate interaction between biotin and streptavidin. MTSEA biotin: 2-((Biotinoyl)amino)ethylmethanethiosulfonate; White solid soluble in DMF or DMSO; Store desiccated at -20°C; C13H23N3O4S3; MW: 381.52.
