KCNMA1/KCa1.1 (1184-1200) Blocking Peptide (#BLP-PC107) is the original antigen used for immunization during Anti-KCNMA1 (KCa1.1) (1184-1200) Antibody (#APC-107) generation. The blocking peptide binds and ‘blocks’ Anti-KCNMA1/KCa1.1 (1184-1200) 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.
