Product Overview
Tag | His |
Host Species | Rat |
Accession | XP_001076062.1 |
Synonym | IFNA5 |
Background | Interferon, alpha 5 (IFNA5) belongs to the alpha/beta interferon family. IFNA5 is the only IFNA subtype detected in normal liver, while a mixture of subtypes is observed in the liver tissue of patients with chronic hepatitis C. Interferons are produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. IFN-alpha, the first cytokine to be produced by recombinant DNA technology, has emerged as an important regulator of growth and differentiation, affecting cellular communication and signal transduction pathways as well as immunological control. Originally discovered as an antiviral substance, the efficacy of IFN-alpha in malignant, viral, immunological, angiogenic, inflammatory, and fibrotic diseases suggests a spectrum of interrelated pathophysiologies. IFN-alpha emerged as a prototypic tumor suppressor protein that represses the clinical tumorigenic phenotype in some malignancies capable of differentiation. |
Description | A DNA sequence encoding the rat IFNA5 (XP_001076062.1) (Met1-Glu189) was expressed, fused with a His tag at the C-terminus. |
Source | HEK293 |
Predicted N Terminal | Cys 24 |
AA Sequence | Met1-Glu189 |
Molecular Weight | The recombinant rat IFNA5 comprises 179 a.a. and predicts a molecular mass of 20.9 kDa. The apparent molecular mass of the recombinant protein is approximately 21 kDa in SDS-PAGE under reducing conditions due to glycosylation. |
Purity | >95% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | Measured in antiviral assay using L929 cells infected with vesicular stomatitisvirus (VSV).The ED50 for this effect is typically 10-50 pg/mL. |
Formulation | Lyophilized from sterile PBS, pH 7.4. |
Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
Usage | For Research Use Only |
Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
