Overview
Type: Synthetic peptide
Form: Lyophilized powder
Kir2.1/KCNJ2 Blocking Peptide (#BLP-PC026) is the original antigen used for immunization during Anti-Kir2.1/KCNJ2 Antibody (#APC-026) generation. The blocking peptide binds and ‘blocks’ Anti-Kir2.1/KCNJ2 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
For research purposes only. not for human use
