<0.10 EU per 1 μg of the protein by the LAL method.
Measured by its ability to induce Topflash reporter activity in HEK293T human embryonic kidney cells. The ED50 for this effect is 2.5-12.5 μg/mL in the presence of 10 ng/mL Recombinant Mouse Wnt‑3a (Catalog # 1324-WN).

Recombinant Human Lgr6 induces Topflashreporter activity in HEK293T human embryonic kidney cells. The ED50 for this effect is2.5-12.5 µg/mL in the presence of 10 ng/mL Recombinant Mouse Wnt-3a (Catalog # 1324-WN).
Lgr6 (leucine‑rich repeat G protein‑coupled receptor 6) is an approximately 100 kDa 7‑transmembrane glycoprotein in the Lgr family of cell surface receptors. Lgrs has been identified as a marker for specific types of stem cells in tissues that are subject to constant self-renewal such as skin, gastrointestinal tract, and lungs (1, 2). The 544 amino acid (aa) N-terminal extracellular domain (ECD) of mature human Lgr6 contains 15 LRRs flanked by N-terminal and C-and C-terminal LRR domains. The ECD is followed by a 7-TM region and a 137 aa C-terminal cytoplasmic domain (3). Within the N-terminal ECD, human Lgr6 shares 92% and 93% aa sequence identity with mouse and rat Lgr6, respectively. Alternative splicing generates an additional isoform with a substitution for the LRR N-terminal domain and a deletion of LRR3-6. Lgr6 is expressed on hair follicle stem cells that give rise to sebaceous glands, interfollicular epidermis, and hair follicles (4-6). It is also expressed on alveolar stem cells that differentiate into lung epithelium (7). It is often up-regulated in human gastric cancers (8). Lgr6 binds to R‑Spondins 1-4 and can enhance Wnt/beta-Catenin signaling through phosphorylation of the Wnt co-receptor LRP6 (9, 10).
