Orexin Receptor 1 Blocking Peptide (#BLP-OR001) is the original antigen used for immunization during Anti-Orexin Receptor 1 Antibody (#AOR-001) generation. The blocking peptide binds and ‘blocks’ Anti-Orexin Receptor 1 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.
