Overview
Type: Synthetic peptide
Form: Lyophilized powder
CCR9 (extracellular) Blocking Peptide (#BLP-CR029) is the original antigen used for immunization during Anti-CCR9 (extracellular) Antibody (#ACR-029) generation. The blocking peptide binds and ‘blocks’ Anti-CCR9 (extracellular) 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
