GPR84 (extracellular) Blocking Peptide (#BLP-GR052) is the original antigen used for immunization during Anti-GPR84 (extracellular) Antibody (#AGR-052) generation. The blocking peptide binds and ‘blocks’ Anti-GPR84 (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.
- Western blot analysis of rat brain membranes (lanes 1 and 4), mouse brain membranes (lanes 2 and 5) and rat spleen membranes (lanes 3 and 6):
- Western blot analysis of human THP-1 monocytic leukemia (lanes 1 and 4), human HL-60 promyelocytic leukemia (lanes 2 and 5) and human U-87 MG glioblastoma (lanes 3 and 6) cell line lysates:
- Expression of GPR84 in mouse fornix in a kainic acid-induced model of temporal lobe epilepsyImmunohistochemical staining of perfusion-fixed frozen mouse brain sections with Anti-GPR84 (extracellular) Antibody (#AGR-052), (1:200), followed by goat anti-rabbit-AlexaFluor-488. A. In untreated mouse sections GPR84 immunoreactivity (green) is detected in astrocyte profiles (arrows). B. GPR84 staining (green) in mouse sections obtained four days post kainate-induced seizures, shows an increase in number and size of astrocyte profiles stained for GPR84 (arrows). Cell nuclei are stained with DAPI (blue).
