The immunohistochemical staining system called Universal Immuno-enzyme Polymer (UIP) method was developed. This is our patented technology.
-Histofine® Simple Stain AP is a detection reagent designed specifically to allow immunohistochemical staining on formalin-fixed paraffin-embedded human tissue sections. It is the labeled polymer prepared by combining amino acid polymer with alkaline phosphatase (AP) and secondary antibody which is reduced to Fab' fragment. To eliminate background staining, solid-phase absorption of secondary antibody is carried out with human serum.
