LPAR6/P2RY5 (extracellular) Blocking Peptide (#BLP-LR036) is the original antigen used for immunization during Anti-LPAR6 (P2RY5) (extracellular) Antibody (#ALR-036) generation. The blocking peptide binds and ‘blocks’ Anti-LPAR6/P2RY5 (extracellular) 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.
