Detection of Human GPER by Western Blot.
Western blot shows lysates of human brain cortex tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human GPER Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5534) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for GPER at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of GPER/GPR30 in HEK293 Human Cell Line Transfected with human GPER/GRP30 and eGFP by Flow Cytometry.
HEK293 human embryonic kidney cell line transfected with (A) human GPER/GRP30 or (B) irrelevant transfectants, and eGFP was stained with Goat Anti-Human GPER/GPR30 Affinity-Purified Polyclonal Antibody (Catalog # AF5534) followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0108). Quadrants were set based on Goat IgG Flow Cytometry Isotype Control (Catalog # AB-108-C, data not shown). View our protocol for Staining Membrane-associated Proteins.
GPER in Human Brain.
GPER was detected in immersion fixed paraffin-embedded sections of human brain (hypothalamus) using Goat Anti-Human GPER Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5534) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

GPER (G-Protein Coupled Estrogen Receptor 1; also GPR30, DRY12 and mER) is a 44 kDa, seven transmembrane (TM) member of the GPR-1 family of molecules. It is ubiquitously expressed, appearing on/in neurons, monocytes and endothelial cells. Its exact location is unclear; it has been described in both the cell membrane and ER, but not by all investigators. Human GPER is 375 amino acids (aa) in length. It contains an N-terminal extracellular region (aa 1‑62), a series of seven TM domains (aa 63‑327), and a C-terminal cytoplasmic tail (aa 328‑375). The initial function attributed to GPER was that of a membrane receptor for estrogen. This is in dispute. There are two potential splice variants for GPER. One shows a deletion of aa 32-49, while a second shows a 99 aa substitution for aa 308‑375. Over aa 1‑62, human GPER shares 57% aa identity with mouse GPER.
