GPR34 in A172 Human Cell Line. GPR34 was detected in immersion fixed A172 human glioblastoma cell line using Mouse Anti-Human GPR34 Monoclonal Antibody (Catalog # MAB4617) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

Detection of GPR34 in A172 Human Cell Line by Flow Cytometry. A172 human glioblastoma cell line was stained with Mouse Anti-Human GPR34 Monoclonal Antibody (Catalog # MAB4617, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: GPR34

GPR34 is a widely expressed 75-90 kDa seven transmembrane segment glycoprotein. It is upregulated on microglia during inflammation and functions as a receptor for lysophosphatidyl-L-serine on mast cells to promote degranulation. Multiple isoforms of GPR34 may result from multiple translation initiation sites and alternative splicing. Human GPR34 shares 89% amino acid sequence identity with mouse and rat GPR34.
