Application

Chromeo P503 is used as a fluorogenic reagent to label primary amine groups within molecules such as proteins. Chromeo P503 labeled proteins may be studied in a variety of gel electrophoresis and chromatographic applications.

Caution

To ensure stability, the lyophilized dye should be stored at 4°C in the dark. This product is guaranteed for 6 months from the date of arrival.

General description

Chromeo P503 labels proteins and peptides by exhibiting a color change from blue to red upon binding to primary amines. Chromeo P503 displays a weak fluorescence with a quantum yield ﹤1% in solution. After conjugation to a primary amine group, the label undergoes a shortwave spectral shift of >100 nm and the quantum yield rises to 50%. This property allows a distinct detection of primary amines, proteins, and other biomolecules.
