Cav2.3/CACNA1E Blocking Peptide (#BLP-CC006) is the original antigen used for immunization during Anti-CaV2.3 (CACNA1E) Antibody (#ACC-006) generation. The blocking peptide binds and ‘blocks’ Anti-Cav2.3/CACNA1E 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.
