Kv1.2/KCNA2 Blocking Peptide (#BLP-PC010) is the original antigen used for immunization during Anti-KV1.2 (KCNA2) Antibody (#APC-010) generation. The blocking peptide binds and ‘blocks’ Anti-Kv1.2/KCNA2 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.

- Multiplex staining of KV1.2 and KV1.1 in mouse cerebellumImmunohistochemical staining of mouse perfusion-fixed frozen brain sections using Anti-KV1.2 (KCNA2) Antibody (#APC-010), (1:300) and Anti-KV1.1 (KCNA1) (extracellular)-ATTO Fluor-594 Antibody (#APC-161-AR), (1:100). A. KV1.2 staining, followed by donkey-anti-rabbit-Cy2 (green). B. KV1.1 staining (red). C. Merge of the two images suggests considerable co-localization in the pinceau structures (up-pointing arrows). KV1.1 also appears in blood vessels (down-pointing arrows), where no KV1.2 expression is observed.
