Fluorescamine *CAS 38183-12-9*
Fluorescamine is a popular amine-fluorogenic reagent for determining protein concentrations in solutions and on gels. It is also used to analyze low molecular weight amines by TLC, HPLC and capillary electrophoresis. Fluorescamine is nonfluorescent but readily reacts with primary aliphatic amines, including those in peptides and proteins, to yield a strongly blue-green fluorescent adduct that can be excited by UV light. The amine adduct has absorption maximum at 385 nm and fluorescence maximum at 486 nm.
Example protocol
AT A GLANCE
Important notes
It is important to store at <-15 °C and should be stored in cool, dark place.
It can be used within 12 months from the date of receipt.
PREPARATION OF WORKING SOLUTION
Fluorescamine working solution:
Add anhydrous DMF or DMSO to make Fluorescamine working solution of desired concentration. Note: Fluorescamine reacts with water and many other aqueous buffers. It is recommended not to make buffer solutions.
