| 确定序列 | Glu31-Arg369 |
| 分子量 | The recombinant Biotinylated Human SIRP alpha V2/CD172a protein with the His-Avi tag at the C-terminus has a predicted MW of 40 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Bis-Tris PAGE result. |
| 活性 | Immobilized recombinant Human CD47 protein with the C-His-Avi tag at 1 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Biotinylated Human SIRP alpha V2 protein with the C-His tag with the EC50 of 0.36 ug/ml determined by ELISA. |
| Form | Lyophilized |
| 形式 | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| 制剂 | It is recommended to reconstitute the lyophilized recombinant Biotinylated Human SIRP alpha V2/CD172a Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening. |
| 纯度 | >95% by SEC-HPLC and SDS-PAGE under reducing conditions. |
| 内毒素 | Less than 1EU per ug by the LAL method. |
| 运输 | The recombinant Biotinylated Human SIRP alpha V2/CD172a Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. |
| 稳定性与储存 | '-20 to -80°C for 12 months as supplied from date of receipt.； -20 to -80°C for 3-6 months in unopened state after reconstitution.； 2-8°C for 2-7 days after reconstitution.； Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
| 注意事项 | Conditions of optimal recombinant Biotinylated Human SIRP alpha V2/CD172a Protein performance should be determined experimentally by the investigator. |

BP004374: Biotinylated Human SIRP alpha V2/CD172a Protein with the C-His-Avi Tag (生物素化人 SIRP α V2/CD172a 蛋白 C-His-Avi 标签)
Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRPα 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 α and inhibit macrophage-mediated destruction.
