Neurotrophin 4/NT-4 Blocking Peptide (#BLP-NT004) is the original antigen used for immunization during Anti-Neurotrophin 4 (NT-4) Antibody (#ANT-004) generation. The blocking peptide binds and ‘blocks’ Anti-Neurotrophin 4/NT-4 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.
