Fluorescent Labeling

Fluorescent dyes are the primary means of labeling biomolecules. The most common such dyes are FITC derivatives, which have a wide range of applications in fluorescence microscopy, flow cytometry, and immunofluorescence-based assays. DGpeptides Co., Ltd. provides many kinds of fluorescent labelings: FITC, FAM, TAMRA etc. Contact us if your fluorescent dye is not on the list


Here are structures for part of them：
