Polyclonal anti-GST reacts with glutathione-S transferase (GST), a common expression tag used in molecular biology. This conjugate is prepared by labeling polyclonal goat anti-GST IgG (H+L) with CF™640R dye. CF™640R (Ex/Em 642/662 nm) is a novel far-red rhodamine-based dye spectrally similar to Cy®5 and Alexa Fluor® 647. CF™640R is much brighter than Cy®5 and at least as bright as Alexa Fluor® 647 when excited at 633 or 635 nm. However, the most important advantage of CF™640R is its exceptional photostability.
