Aquaporin 7 Blocking Peptide (#BLP-QP007) is the original antigen used for immunization during Anti-Aquaporin 7 Antibody (#AQP-007) generation. The blocking peptide binds and ‘blocks’ Anti-Aquaporin 7 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.
