UBQ-2 NHS Ester Chemical Properties,Usage,Production

Description

UBQ-2 NHS Ester is a dark quencher with no native emission due to the polyaromatic-azo backbone and a terminal NHS ester. UBQ-2 NHS Ester has a wide and intense quenching range from 560-670 nm, which makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with orange to far-red emitting dyes. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
