Fluorescent Dyes  >  HiLyte Fluor™ Dyes  >>  HiLyte Fluor™ 488 hydroxylamine, HCl salt *single isomer*

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.
