| Description | The R-Spondin (Rspo) proteins belong to the Rspo family of Wnt modulators. Currently, the family consists of four structurally related secreted ligands (Rspo 1-4), all containing furin-like and thrombospondin structural domains. The Rspo proteins can interact with the Frizzled/LRP6 receptor complex in a manner that causes the stabilization and resulting accumulation of the intracellular signaling protein, beta-catenin. This activity effectively activates and increases the subsequent nuclear signaling of beta-catenin. R-Spondin can also bind to the previously discovered G-protein coupled receptors, LGR-4 and LGR-5. Rspo/beta-catenin signaling can act as an inducer of the transformed phenotype, and can also regulate the proliferation and differentiation of certain stem cell populations. Recombinant human R-Spondin-3 is a 26.9kD protein consisting of 240aa residues. Due to glycosylation, R-Spondin-3 migrates at an apparent molecular weight of approximately 37kD by SDS PAGE analysis under reducing conditions. Biological Activity: R-Spondin-3 enhances BMP-2 mediated differentiation of MC3T3-E1 cells.

Endotoxin: <0.1ng/ug of protein (<1EU/ug). Protein Content: Verified by UV Spectroscopy and/or SDS-PAGE gel. Storage and Stability: Store lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein. | ||
