Antisera for IHC

Rabbit Polyclonal Santa Cruz LHR (H-50): sc-25828 sc-25828

"recommended for detection of LHR of mouse, rat and human origin by WB, IP, IF, IHC(P) and ELISA"

Santa Cruz also has several goat anti-LHR antibodies, but not sure they work for IHC (although listed for immunofluroescence).
