Intracellular Staining by Flow Cytometry
|Detection of GPR50 in A172 Human Cell Line by Flow Cytometry. A172 human glioblastoma cell line was stained with Mouse Anti-Human GPR50 Monoclonal Antibody (Catalog # MAB4645, filled histogram) or isotype control antibody (Catalog # MAB0031, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2 Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.|
|GPR50 in A172 Human Cell Line. GPR50 was detected in immersion fixed A172 human glioblastoma cell line using 10 µg/mL Mouse Anti-Human GPR50 Monoclonal Antibody (Catalog # MAB4645) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel).

GPR50, also known as MTR1L, is a non-glycosylated seven-transmembrane G protein-coupled receptor that is related to the melatonin receptors MT1 and MT2. GPR50 is expressed in the hippocampus, hypothalamus, and pituitary and forms 130 kDa homodimers. It heterodimerizes with either MT1 or MT2, resulting in inhibition of MT1 but not MT2 function. An alternately spliced isoform of GPR50 has a 4 aa deletion in the large C-terminal cytoplasmic domain. The presence of this deletion as well as various polymorphisms have been associated with elevated serum triglyceride and HDL levels. The deletion may also be associated with the development of bipolar disorder. Human GPR50 shares approximately 70% amino acid sequence identity with mouse and rat GPR50.
