Product Description	Recombinant Rat CD47 Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Gln19-Lys140.
Product Background	CD47 (Cluster of Differentiation 47) also known as integrin associated protein (IAP) is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 (TSP-1) and signal-regulatory protein alpha (SIRPα).CD-47 acts as a don't eat me signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers.
Product Category	Recombinant Protein

Target	CD47
Gene/Protein ID	P97829-1
Species	Rat
Exact Sequence	Gln19-Lys140
Molecular Weight	The protein has a predicted MW of 40.40 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.
Activity	Immobilized Mouse SIRP alpha, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Rat CD47, hFc Tag with the EC50 of 29.8ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-hFc
Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22 um 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.
