sloβ2/KCNMB2 Blocking Peptide (#BLP-PC034) is the original antigen used for immunization during Anti-sloβ2 (KCNMB2) Antibody (#APC-034) generation. The blocking peptide binds and ‘blocks’ Anti-sloβ2/KCNMB2 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.
