Product Description	Recombinant Human R spondin 1/RSPO1 Protein is expressed from CHO with His tag at the C-Terminus.It contains Arg31-Ala263.
Product Background	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.
Product Category	Recombinant Protein

Target	R spondin 1/RSPO1
Synonyms	R-spondin-1; RSPO1; CRISTIN3; FLJ40906; RP11-566C13.1; RSPO
Gene/Protein ID	Q2MKA7
Species	Human
Exact Sequence	Arg31-Ala263
Molecular Weight	The protein has a predicted MW of 27.3 kDa. Due to glycosylation, the protein migrates to 38-42 kDa based on Tris-Bis PAGE result.
Activity	Immobilized Human R spondin 1, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Anti-R spondin 1 Antibody, hFc Tag with the EC50 of 2.9ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	C-His
Express System	CHO
Purity	> 95% as determined by Tris-Bis PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

	Immobilized Human R spondin 1, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Anti-R spondin 1 Antibody, hFc Tag with the EC50 of 2.9ng/ml determined by ELISA (QC Test).
	Immobilized Human R spondin 1, His Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human RNF34, hFc Tag with the EC50 of 0.4ug/ml determined by ELISA.
	Measured by its ability to induce Topflash reporter activity in HEK293T human embryonic kidney cells. The ED50-for this effect is 1.0 - 10.0 ng/mL in the presence of 5 ng/mL recombinant Human Wnt Surrogate-Fc Fusion (WNT-HM23A) (QC Test).
	Human R spondin 1 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
