| Product Name: | R-Spondin-1 (Rspo-1) |
| Description: | Recombinant Human R-Spondin-1 is a 26.7 kDa protein consisting of 243 amino acid residues. Due to glycosylation, R-Spondin-1 migrates at an apparent molecular weight of approximately 40.0 kDa by SDS-PAGE analysis under reducing conditions. |

| Introduction: | R-Spondin-1 (Rspo-1) belongs to the (Rspo) family of Wnt modulators. Currently, the family consists of four structurally related secreted ligands (Rspo 1-4), all containing the furin-like and thrombospondin structural domains. Rspo-1 is expressed in certain areas of the developing central nervous system, as well as in the adrenal glands, ovary, testis, thyroid, and trachea. Rspo can interact with the Frizzled/LRP6 receptor complex in a manner that stimulates the Wnt/β-catenin signaling pathway. |
| Purity: | ≥ 95% by SDS-PAGE gel and HPLC analyses. |
| Biological Activity: | Assay #1: R-Spondin-1 enhances BMP-2-mediated differentiation of MC3T3-E1 cells. The expected ED50 is 1.0-3.0 μg/ml. Assay #2: Measured by its ability to induce Topflash reporter activity in HEK293 TCF/LEF Luc reporter cells. The ED50 for this effect is typically 0.6-1.0 μg/ml in the presence of 50 ng/ml recombinant human BMP-2. |
