Biosearch Technologies is pleased to announce that we are offering protein labeling kits using our recently developed water soluble Quasar® WS dyes. These fluorescent dyes have charged substituents that add water solubility and resistance to self-quenching. Quasar 570WS and Quasar 670WS will be provided as succinimidyl active esters for labeling amine groups on proteins and other substrates.
