Kv6.4 (KCNG4) Blocking Peptide (#BLP-PC138) is the original antigen used for immunization during Anti-Kv6.4 (KCNG4) Antibody (#APC-138) generation. The blocking peptide binds and ‘blocks’ Anti-Kv6.4 (KCNG4) 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.

A. Kv6.4 immunoreactivity (red) appears in the wall of the aqueduct (arrow). B. Pre-incubation of the antibody with Kv6.4 (KCNG4) Blocking Peptide (BLP-PC138), suppressed staining. Cell nuclei are stained with DAPI (blue).
