Nicotinic Acetylcholine Receptor α2/CHRNA2 (extracellular) Blocking Peptide (#BLP-NC002) is the original antigen used for immunization during Anti-Nicotinic Acetylcholine Receptor α2 (CHRNA2) (extracellular) Antibody (#ANC-002) generation. The blocking peptide binds and ‘blocks’ Anti-Nicotinic Acetylcholine Receptor α2/CHRNA2 (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.
