What are the extinction coefficients for dansylated amino acids?

13 September 2018 1 4K Report

I'm trying to confirm the concentrations of some dansylated amino acid stocks and am looking for some sources for their extinction coefficients and absorption wavelengths. Any help is appreciated.

Isam Eldin Hussein Elgailani

Dear Sir. Concerning your issue about the extinction coefficients for dansylated amino acids. The decomposition of the dansylated amino acid in reaction leads to ... is determined spectrophotometrically, using an extinction coefficient of 3.67 x 10° at 369 nm. I think the following below links may help you in your analysis:
