2-[(5-Fluoresceinyl)aminocarbonyl]ethyl Methanethiosulfonate (MTS-4-Fluorescein)
10mg
Molecular Biology Storage: -20CShipping: RT
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
