| Signal regulatory protein ? (SIRP?) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRP? acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don´t eat me" signal.Cancer cells highly expressed CD47 that activate SIRP ? and inhibit macrophage-mediated destruction. |
| Recombinant Human SIRP alpha V4 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Glu31-Arg370(E33G, L44S, T50S, T52I, R54H). |

| The protein has a predicted MW of 39.8 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on the Tris-Bis PAGE result. |
|
| Immobilized Human SIRP alpha V4, His Tag at 1ug/ml (100ul/Well). Dose response curve for Human CD47, hFc Tag with the EC50 of 44.3ng/ml determined by ELISA. See testing image for detail. |

| Less than 1EU per ug by the LAL method. |
|
| Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization. |
|
| 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. |
|
| Shipped at ambient temperature. |
|
| Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
