This reagent reacts with amine compounds such as amino acids, peptides and proteins to give bright red fluorescent conjugates that are extremely stable, and resistant to protease-catalyzed hydrolysis.

Solid. Soluble in DMF. Caution: Do not dissolve in DMSO. Sulforhodamine 101 sulfonyl chloride (also called Texas Red sulfonyl chloride) is a popular long wavelength amine-reactive rhodamine dye. Because the dye is quite unstable in water, reactions with amines in an aqueous solution must be carried out at low...

Sulforhodamine 101 sulfonyl chloride is a fluorescent probe that binds to free amino groups and is a derivative of sulforhodamine 101 (Cay-16953). It displays excitation/emission maxima of 585/602 nm, respectively. Sulforhodamine 101 sulfonyl chloride has commonly been used as a fluorescent conjugate on antibodies...
