CHRM4 Blocking Peptide (#BLP-MR004) is the original antigen used for immunization during Anti-CHRM4 Antibody (#AMR-004) generation. The blocking peptide binds and ‘blocks’ Anti-CHRM4 primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.

- Expression of Muscarinic acetylcholine receptor M4 in mouse islands of CallejaImmunohistochemical staining of mouse islands of Calleja (ventral striatum) using Anti-CHRM4 Antibody (#AMR-004). A. M4 mAChR staining (red) appears in soma of neuronal profiles (vertical arrows) and a diffuse halo (horizontal arrows) in the vicinity of the islands of Calleja (IC). B. Nuclear staining using DAPI as the counterstain. C. Merged image of A and B.
