CLC-1/CLCN1 Blocking Peptide (#BLP-CL005) is the original antigen used for immunization during Anti-CLC-1 (CLCN1) Antibody (#ACL-005) generation. The blocking peptide binds and ‘blocks’ Anti-CLC-1/CLCN1 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.
