| | Dansyl ethylenediamine Usage And Synthesis |
| Description | Dansyl ethylenediamine is a lipophilic fluorophore that can be coupled to coarboxylic acids of proteins and other water-soluble polymers. The primary aliphatic amine of dansyl ethylenediamine can be reversibly coupled to aldehydes and ketones to form a Schiff base, which can be reduced to a generate stable amine derivative by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaCNH3). Spectral data: λex=335nm, λem=525nm in methanol. Dansyl ethylenediamine has also shown to inhibit human renal dipeptidase (hrDP) irreversibly in a time-dependent manner. | | Chemical Properties | Yellow to orange powder. | | Uses | A fluorescent reagent. | | References | [1] YUKI INOUE.
