Polyclonal anti-GST is designed to detect glutathione-S transferase (GST), a common expression tag used in molecular biology. This product is prepared by labeling high quality polyclonal goat anti-GST IgG (H+L) with the red fluorescent dye CF594. CF594 is spectrally similar to Alexa Fluor? 594 and Texas Red? dye but yields much brighter protein conjugates due to its high quantum yield and exceptional water solubility. CF594 also has excellent photostability ideal for demanding applications, such as confocal microscopy and single molecule imaging.
