Overview
Cat #: BLP-QP004
Type: GST fusion protein
Form: Lyophilized powder
Aquaporin 4/AQP4 (249-323) Blocking Peptide (#BLP-QP004) is the original antigen used for immunization during Anti-Aquaporin 4 (AQP4) (249-323) Antibody (#AQP-004) generation. The blocking peptide binds and ‘blocks’ Anti-Aquaporin 4/AQP4 (249-323) 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.
Applications: wb, ihc
