TRPP1/PKD2 Blocking Peptide (#BLP-CC052) is the original antigen used for immunization during Anti-TRPP1 (PKD2) Antibody (#ACC-052) generation. The blocking peptide binds and ‘blocks’ Anti-TRPP1/PKD2 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.
