Human GPER/GPR30 Antibody Summary
Accession # Q99527
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
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.
