Cav3.3/CACNA1I Blocking Peptide (#BLP-CC009) is the original antigen used for immunization during Anti-CaV3.3 (CACNA1I) Antibody (#ACC-009) generation. The blocking peptide binds and ‘blocks’ Anti-Cav3.3/CACNA1I 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 CaV3.3 in mouse hippocampus.Immunohistochemical staining of perfusion-fixed frozen mouse brain sections with Anti-CaV3.3 (CACNA1I) Antibody (#ACC-009), (1:400), followed by donkey anti-rabbit-Cy3. A. Staining in the hippocampal CA3 region, showed Cav3.3 immunoreactivity (red) appeared in soma of pyramidal neuron profiles (horizontal arrows) and in dendrites (vertical arrows) projecting into the stratum radiatum (SR). B. Pre-incubation of the antibody with Cav3.3/CACNA1I Blocking Peptide (#BLP-CC009), suppressed staining. Cell nuclei are stained with DAPI (blue). P = pyramidal layer.
