KCNK3/TASK-1 Blocking Peptide (#BLP-PC024) is the original antigen used for immunization during Anti-KCNK3 (TASK-1) Antibody (#APC-024) generation. The blocking peptide binds and ‘blocks’ Anti-KCNK3/TASK-1 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.
