Human R spondin 3/RSPO3 Protein
Recombinant Human R spondin 3/RSPO3 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln22-Val146.[Accession | Q9BXY4-1]
The protein has a predicted MW of 14.95 kDa. Due to glycosylation, the protein migrates to 20-25 kDa and 26-32 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human R spondin 3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
Immobilized Human R-Spondin 3, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human RNF43, hFc Tag with the EC50 of 25.2ng/ml determined by ELISA (QC Test).
Human LGR-5, hFc Tag captured on CM5 Chip via Protein A can bind Human R-Spondin 3, His Tag with an affinity constant of 0.59 nM as determined in SPR assay (Biacore T200) (Routine Test).
The R-spondins are members of a superfamily of thrombospondin type 1 repeat (TSR-1)-containing proteins. The prototype member (discovered in 1971) was isolated from platelets that had been stimulated with thrombin, and was therefore designated 'thrombin-sensitive protein.
