Biological Activity
IFN-alpha 2a, Human (Cat. No. Z03003) induced cytotoxicity of R&D TF-1 cells. The ED50 for this effect is less than 0.1ng/mL. »
2 μg of IFN-α 2a, Human (Cat. No. Z03003) was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie Blue staining. »
| Target Background | Interferon-Alpha 2a (IFN-Alpha 2a), Human produced by leukocytes is a member of Interferon family. IFN-alpha is mainly involved in innate immune response against a broad range of viral infections. IFN-alpha 2 has three acid stable forms (a,b,c) signaling through IFNAR2. IFN-alpha 2a shares 99.4% , 98.8% aa sequence identity with IFN-alpha 2b and 2c respectively. IFN-alpha contains four highly conserved cysteine residues which form two disulfide bonds, one of which is necessary for biological activity. |
| Synonyms | Leukocyte interferon; B cell interferon; Type I interferon; IFNA2; IFN-a 2a |
For laboratory research use only. Direct human use, including taking orally and injection and clinical use are forbidden.
