CHRM2 Blocking Peptide (#BLP-MR002) is the original antigen used for immunization during Anti-CHRM2 Antibody (#AMR-002) generation. The blocking peptide binds and ‘blocks’ Anti-CHRM2 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 M2 in mouse parieto-temporal cortex sectionsImmunohistochemical staining of mouse parieto-temporal cortex frozen sections (non-consecutive) using Anti-GIRK2 (Kir3.2) Antibody (#APC-006), (1:100) and Anti-CHRM2 Antibody (#AMR-002), (1:100). mAChR M2 staining (red) was dense in layer IV, with fibers climbing to layers II-III. Kir3.2 K+ channel staining (green) was dense in layers IV and I. Overlapping expression of Kir3.2 channel and mAChR M2 is seen in cortical layers.
