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 / Antibody discovery

Protein	R spondin 1/RSPO1
Synonyms	R-spondin-1; RSPO1; CRISTIN3; FLJ40906; RP11-566C13.1; RSPO; R-Spondin1
Accession	Q2MKA7
Species	Human
Biotinylated	no
Amino Acid Range	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 Bis-Tris 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
Expression System	CHO
Purity	> 95% as determined by Bis-Tris PAGE
Endotoxin	Less than 0.05EU 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	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
