Detection of Lgr5/GPR49 in HEK293 Human Cell Line Transfected with Mouse Lgr5/GPR49 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with mouse Lgr5/GPR49 and eGFP was stained with and either (A) Rat Anti-Mouse Lgr5/GPR49 Monoclonal Antibody (Catalog # MAB8240) or (B) Rat IgG2BIsotype Control (Catalog # MAB0061) followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113).
Lgr5/GPR49 in HEK293 Human Cell Line Transfected with Mouse Lgf5/GPR49. Lgr5/GPR49 was detected in immersion fixed HEK293 human embryonic kidney cell line transfected with GFP (green) tagged mouse LGR5 using Rat Anti-Mouse Lgr5/GPR49 Monoclonal Antibody (Catalog # MAB8240) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Lgr5/GPR49 in Mouse Cells Transfected with Mouse Lgr5/GPR49. Lgr5/GPR49 was detected in immersion fixed MYC tagged mouse transfectants using Rat Anti-Mouse Lgr5/GPR49 Monoclonal Antibody (Catalog # MAB8240). Cells were stained using an anti-Mouse HRP-conjugated secondary antibody (brown).Image courtesy of Dr. Hans Clevers, Hubrecht Institute, The Netherlands.
Mouse Lgr5/GPR49 Antibody Induces Activity. Rat Anti-Mouse Lgr5/GPR49 Monoclonal Antibody (Catalog # MAB8240) induces TOPflash activity in the HEK293 human embryonic kidney cell line stably expressing LGR5 in the presence of Wnt-3a, but in the absence of R-Spondins.

Leucine‑rich repeat G‑protein‑coupled receptor 5 (Lgr5), also called GPR49, is a 907 amino acid (aa), approximately 97 kDa (calculated), seven‑transmembrane glycoprotein receptor in the Lgr family of cell surface receptors. The subfamily of Lgrs comprising Lgr4, Lgr5, and Lgr6 are G‑protein‑independent mediators of the potentiating effect of R‑Spondins on Wnt signaling (2). Lgr5 binds and forms complexes with R‑Spondins, Frizzled Wnt receptors and LRP Wnt co‑receptors. The region of the mouse Lgr5 long extracellular domain used as an immunogen shares 90% and 95% amino acid sequence identity with human and rat Lgr5, respectively. Lgr5 is found on embryonic and adult epithelial stem cells (3). Lgr5+ stem cells can produce all epithelial cell types of the intestinal crypts (4). It is upregulated in stem cells that give rise to cancers such as intestinal, hepatocellular, pancreatic and ovarian carcinomas (5,6). This antibody has been referred to as "RD20" by Peng et al.(1).
