(L)-2-[(t-Boc)amino]-2-[(5-Fluoresceinyl)aminocarbonyl]ethyl Methanethiosulfonate

Controlled Product

CAS: 1042688-20-9

Stability Light Sensitive
Applications A thiol specific fluorescent probe useful for ion channel and protein topology research. The recently available MTS-fluorophores may find application in the real-time monitoring of conformational changes, since fluorophores coupled to introduced cysteines can change their fluorescence during a conformational change. Fluorescence lifetime may also yield information regarding distances and molecular motion in a protein molecule.Fluorescence: max. Abs. 492nm; max. Em. 515nm; e x 10-3: 75
