Polyclonal anti-GST is designed to detect glutathione-S transferase (GST), a common expression tag used in molecular biology. These products are prepared by labeling high quality polyclonal goat anti-GST with CF® dyes. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. • Green fluorescent CF®488A dye has excitation/emission at 490/515 nm. • Deep-red fluorescent CF®594 dye has excitation/emission at 593/614 nm. • Far-red fluorescent CF®640R dye has excitation/emission at 642/662 nm. • Far-red/near-infrared fluorescent CF®680 dye has excitation/emission at 681/698 nm. • Near-infrared fluorescent CF®770 dye has excitation/emission at 770/797 nm.
