GDNF Blocking Peptide (#BLP-NT014) is the original antigen used for immunization during Anti-GDNF Antibody (#ANT-014) generation. The blocking peptide binds and ‘blocks’ Anti-GDNF 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.
