| 来源 | The recombinant Human CD21 Protein, (amino acids Ile21-Arg971) fused with a His tag at the C-terminus, was produced in HEK 293 cells. |
| Accession | P20023-1 |
| 产品标签 | C-His |
| 生物素化 | no |
| 确定序列 | Ile21-Arg971 |
| 分子量 | The recombinant Human CD21 protein with the His tag at the C-terminus has a predicted MW of 105.3 kDa. Due to glycosylation, the protein migrates to 110-130 kDa based on Bis-Tris PAGE result. |
| 活性 | Immobilized recombinant Human CD21 protein with the C-His tag at 0.5 ug/ml (100 ul/Well) on the plate. Dose response curve for the recombinant Anti-CD21 Antibody protein with the C-hFc tag with the EC50 of 7.9 ng/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 Human CD21 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 1 EU per ug of protein as determined by LAL method. |
| 运输 | The recombinant Human CD21 Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. |
| 稳定性与储存 | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 week, 2 to 8°C under sterile conditions after reconstitution. 6 months, -20 to -70°C under sterile conditions after reconstitution. |
| 注意事项 | Conditions of optimal recombinant Human CD21 Protein performance should be determined experimentally by the investigator. |

文献
BP004854: Human CD21 Protein with the C-His Tag (人 CD21 蛋白 C-His 标签)
CD21 mRNA expression, an EBV-entry receptor, was transiently detected in NK cells after exosome treatment, and levels decreased after further culture. CD21 protein expression was also transiently transferred to NK cells after co-culture with an EBV-positive Burkitt lymphoma cell line (Raji) via trogocytosis. However, EBV did not infect NK cells through CD21-mediated trogocytosis.
