Human TRPV2/VRL1 (extracellular) Blocking Peptide (#BLP-CC139) is the original antigen used for immunization during Anti-Human TRPV2 (VRL1) (extracellular) Antibody (#ACC-139) generation. The blocking peptide binds and ‘blocks’ Anti-Human TRPV2/VRL1 (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.
