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 PointAs reported
Solubility10mg in 250ul DMSO and add 50ml Water, DMSO, Methanol
Method for Determining IdentityProton NMR (DMSO-d6), Spectroscopic and Mass Spectrometric Analysis
TLC ConditionsAs Reported
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. Store under inert atmosphere.
