Synthetic controls for immunohistochemistry

Provided herein are methods for generating a solid antigen/carrier protein gel for immunohistochemistry (IHC) staining, as well as gels, kits and methods of use thereto. In particular, the methods, gels and kits provided herein include a purified antigen such as a polypeptide antigen, and a carrier protein such as a serum albumin protein, an egg white protein or mixture of egg white proteins, gelatin, or poly-lysine. Examples are provided in which the purified antigen is cross-linked to the carrier protein in the solid antigen/carrier protein gel.
