产品名称:
R-Spondin-3 Recombinant Protein
别名:
Roof plate-specific spondin-3, RSPO3, PWTSR, THSD2
表达系统:
CHO cells
保存温度:
The recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

功能与背景:
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, β-catenin. This activity effectively activates and increases the subsequent nuclear signaling of β-catenin. R-Spondin can also bind to the previously discovered G-protein coupled receptors, LGR-4 and LGR-5. Rspo/β-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 26.9 kDa protein consisting of 240 amino acid residues. Due to glycosylation, R-Spondin-3 migrates at an apparent molecular weight of approximately 37.0 kDa by SDS PAGE analysis under reducing conditions.
纯度:
≥ 95% by SDS-PAGE gel and HPLC analyses.
生物活性:
R-Spondin-3 enhances BMP-2-mediated differentiation of MC3T3-E1 cells. The expected ED50 for this effect is 0.8 – 2.0 ug/ml.
