K-Gold® Substrate is a one-bottle stabilised chromogenic substrate for use with alkaline phosphatase based immunoassays. K-Gold Substrate utilises the substrate p-nitrophenyl-phosphate (PNPP), which reacts with alkaline phosphatase to produce the chromophore p-nitrophenol. Neogen’s ready-to-use K-Gold formula does not require mixing of additional ingredients or stabilising agents, making it an ideal formula for kit manufacturers.
