| 分子量 | The recombinant Human Factor H/CFH protein with the His tag at the C-terminus has a predicted MW of 42.8 kDa. Due to glycosylation, the protein migrates to 60-68 kDa based on Tris-Bis PAGE result. |
| 活性 | Immobilized recombinant Human Factor H protein with the C-His tag at 2 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Anti-Factor H Antibody protein with the C-hFc tag with the EC50 of 7.1 ng/ml determined by ELISA. |
| Form | Lyophilized |
| 形式 | Lyophilized from 0.22 um 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 Factor H/CFH 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 Factor H/CFH 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 Factor H/CFH Protein performance should be determined experimentally by the investigator. |

BP004500: Human Factor H/CFH Protein with the C-His Tag (人因子 H/CFH 蛋白 C-His 标签)
Factor H is the major soluble inhibitor of complement, where its binding to self markers (i.e., particular glycan structures) prevents complement activation and amplification on host surfaces. Not surprisingly, mutations and polymorphisms that affect recognition of self by factor H are associated with diseases of complement dysregulation, such as age-related macular degeneration and atypical haemolytic uremic syndrome. In addition, pathogens (i.e., non-self) and cancer cells (i.e., altered-self) can hijack factor H to evade the immune response.
