BP Fluor 488 Hydroxylamine (aminooxy) is a poplar reagent for labeling aldehydes or ketones in polysaccharides or glycoproteins by forming oximes. Oximes are superior to hydrazones with respect to hydrolytic stability. The dye has an excitation peak at 499 nm and an emission peak at 520 nm. The conjugates are widely used in microscopy, flow cytometry, and other applications. BP Fluor 488 is a pure 5- sulfonated rhodamine molecule and it eliminates the lot-to-lot variation caused by two isomers ratio differences.
