The GelCode kit range includes four general protein-staining kits: Blue Stain, E-Zinc™ Reversible Stain, SilverSNAP™, and Color Silver Stain. The Blue Stain Kit offers one-step staining in one hour and can detect as little as 8 ng of protein. The remaining kits in this group can be used to detect subnanogram quantities of protein. Protein can be detected in only 15 minutes using the E-Zinc Reversible Stain Kit, and after an "eraser" step, can be eluted from the gel free of contamination. While SilverSNAP staining takes only 90 minutes, color silver staining for polychromatic staining of proteins takes considerably longer, but is the more sensitive of the two methods and is useful for distinguishing proteins of similar molecular weight.
Three kits for in-gel staining of proteins bearing specific moieties are new to the GelCode line: the 6xHis Protein Tag, Phosphoprotein, and Glycoprotein Staining Kits. Detection of such proteins usually depends ...
