Neurokinin 2 Receptor/NK2R Blocking Peptide (#BLP-TR002) is the original antigen used for immunization during Anti-Neurokinin 2 Receptor (NK2R) Antibody (#ATR-002) generation. The blocking peptide binds and ‘blocks’ Anti-Neurokinin 2 Receptor/NK2R 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.
