CACNA1B/Cav2.2 Blocking Peptide (#BLP-CC002) is the original antigen used for immunization during Anti-CACNA1B (CaV2.2) Antibody (#ACC-002) generation. The blocking peptide binds and ‘blocks’ Anti-CACNA1B/Cav2.2 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 CaV2.2 in mouse cerebellumImmunohistochemical staining of mouse cerebellum with Anti-CACNA1B (CaV2.2) Antibody (#ACC-002), (1:100). A. CaV2.2 (red) appears in Purkinje cells (arrows) and is distributed diffusely in the molecular layer (Mol). B. Staining of Purkinje cells with mouse anti-Calbindin 28K (green) demonstrates the restriction of CaV2.2 to cell bodies but not to dendrites in the molecular layer. C. Merged image of panels A and B.
