| Formulation | Lyophilized from sterile PBS, pH 7.4. |
| Molecular weight | 19.3 kDa |
| Usage notes | Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IFN alpha 2 protein in sterile ddH2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Storage instructions | Lyophilized Human IFN-α2 proteinshould be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.78% HSA or BSA). Please prevent freeze-thaw cycles. |
| Shipping | The product is shipped at ambient temperature. |

| Background | Human interferon α-2 (IFNα2) is a cytokine belonging to the family of type I IFNs. IFNα2 is a protein secreted by cells infected by a virus and acting on other cells to inhibit viral infection. The first description of IFNs as a cellular agent interfering with viral replication was made by Alick Isaacs and Jean Lindenmann in 1957. The history of this finding was recently reviewed. There are 3 types of IFNs: Interferon type I, Interferon type II and Interferon type III. The type II IFN, also called IFNγ, is produced by specific cells of the immune system. Unlike type I and type III IFNs, IFNγ has only a modest role in directly restricting viral infections. Type I and type III IFNs act similarly. However, the action of type III IFNs, also known as IFNλ, is limited to epithelial cells while type I IFNs act on all body's cells. |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
