R-Spondin-1 (Rspo1) is a part of the Rspondin family. Rspo1 plays a role as an activator of the canonical Wnt signaling pathway by acting as a ligand for LGR4-6 receptors. Rspo1 induces the onset of crypt cell proliferation and increases intestinal epithelial healing effect. Rspo1 is negatively regulating the TGF-beta pathway.
R-Spondin-1 Human Recombinant produced in CHO cells is a glycosylated monomer chain containing 243 amino acids and having a total molecular mass of 25.6kDa.
RSPO1 is purified by proprietary chromatographic techniques.
The protein was lyophilized from a sterile (0.2µm) filtered solution containing PBS.
It is recommended to reconstitute the lyophilized RSPO1in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized RSPO1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution RSPO1 should be stored at 4°C between 2-7 days and for future use below -18°C.
Please prevent freeze-thaw cycles.
