Produktbeschreibung

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 Synonyms: MTSEA-Fluorescein Trifluoroacetic Acid Salt CAS Number: 1356019-48-1 Free Base: 1356019-47-0 Molecular Formula: C26H21F3N2O10S2 Molecular Weight: 642.58 Purity: 95% Appearance: Yellow to orange solid Melting Point: >130C (dec.)
