HiLyte™ Fluor 488 hydroxylamine is a carbonyl-reactive labeling dye, which reacts more readily with aldehydes at physiological pH than other primary amine-containing reagents (such as hydrazides and amines). The reaction of HiLyte™ Fluor 488 hydroxylamine with aldehydes yields oxime ethers, which are stable at physiological conditions. Therefore, HiLyte™ Fluor 488 hydroxylamine can be used to directly detect aldehydes in proteins and DNA. Extinction Coefficient (M-1cm-1): 70,000 Fluorescence quantum yield: 0.91 Fluorescence Life Time (ns): 4.1
