| 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 the signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers. |
| Source
|
Recombinant Human CD47 is expressed from Expi293 with His tag at the C-terminal. It contains Gln19-Pro139. |
| Molecular Weight
|
The protein has a predicted MW of 14.5 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Tris-Bis PAGE result. |
| Endotoxin
|
Less than 1 EU per μg by the LAL method. |
| Purity
|
>95% as determined by Tris-Bis PAGE. |
| Formulation
|
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
| Reconstitution
|
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage
|
-20 to -80℃ for 12 months as supplied from the date of receipt.
-20 to -80℃ for 3-6 months in an unopened state after reconstitution.
2-8℃ for 2-7 days after reconstitution. |
| Notes
|
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. |
