Information: PolyTek Anti-Rabbit Polymerized Alk-Phos has been developed to provide the cleanest, most consistent staining available. Developed in the research laboratories of ScyTek, the system is based on a polymerized alkaline phosphatase label that eliminates biotin and its’ associated background issues from the equation. In addition, this product reduces the steps required for immunohistochemical staining by combining two steps from the traditional Biotin-Streptavidin system. PolyTek Anti-Rabbit Polymerized Alk-Phos is effective with antibodies of rabbit or guinea pig origin.
