Specifications

Catalog #F5254-01
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
Melting Point 174-181°C (dec.)
Solubility DMSO, Methanol
Method for Determining IdentityProton NMR Spectroscopic analysis
TLC Conditions SiO2; Dichloromethane: Methanol=9:1; Visualized with UV. Single spot Rf=0.55
Storage and StabilityMay be stored at RT for short-term only. Long-term storage is recommended at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Moisture and light sensitive.
