CLC-3/CLCN3 Blocking Peptide (#BLP-CL001) is the original antigen used for immunization during Anti-CLC-3 (CLCN3) Antibody (#ACL-001) generation. The blocking peptide binds and ‘blocks’ Anti-CLC-3/CLCN3 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.
