Recombinant Human R-spondin-3/RSPO3 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Gln22-Ala201) of Human RSPO3 fused with a FC-6His tag at the C-terminus.
Pureté
> 95 % as determined by reducing SDS-PAGE.
Stérilité
0.2 μm filtered
niveau d'endotoxine
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
RSPO3
Origine: Humain
Hôte: HEK-293 Cells
Recombinant
The purity of the protein is greater than 95 % as determined by SDS-PAGE and Coomassie blue staining.
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM PB,150 mM NaCl, pH 7.2.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Stock

Stockage commentaire
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
R-spondin-3 (RSPO3), also known as Protein with TSP type-1 repeat, Roof plate-specific spondin-3, Thrombospondin type-1 domain-containing protein 2, PWTSR, THSD2 and CRISTIN1, is a member of the thrombospondin type 1 repeat supergene family. RSPO3 is a secreted protein and widely expressed in many tissues. RSPO3 contains two Furin-like repeats which have been found in a variety of eukaryotic proteins involved in the mechanism of signal transduction by receptor tyrosine kinases, and one TSP type-1 domain, RSPO3 founctions as a activator of the beta-catenin signaling cascade, leading to TCF-dependent gene activation. Otherwise, RSPO3 may negatively regulate the TGF-beta pathway.
