| About this Antibody | |
| Name | Recombinant Human IFN-λ1/IL-29 (Recombinant Human Interferonλ1/Interleukin-29; rHuIFN-λ1/IL-29)；重组人干扰素1/白细胞介素29 |
| Synonyms | IFN-lambda 1; cytokine Zcyto21; IFNL1; IFN-lambda-1; IL-29; interferon lambda-1; interferon, lambda 1; interleukin 29 (interferon, lambda 1); interleukin-29; ZCYTO21 |
| Purity | >97% by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by an anti-viral assay using human HepG2 cells infected with encephalomyocarditis is less than 5ng/ml, corresponding to a specific activity of >2.0×105IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2μM filtered concentrated solution in PBS, pH7.4. |
| Endotoxin | Less than 1EU/μg of rHuIFN-λ1/IL-29 as determined by LAL method. |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions. |
| Category | Cytokine |
| Background | IL-28A, IL-28B, and IL-29, also named interferon-λ2 (IFN-λ2), IFN-λ3, and IFN-λ1, respectively, are newly identified class II cytokine receptor ligands that are distantly related to members of the IL-10 family (11-13%a.a. sequence identity) and the type I IFN family (15-19%a.a. sequence identity). The expression of IL-28A, B, and IL-29 is induced by virus infection or doublestranded RNA. All three cytokines exert bioactivities that overlap those of type I IFNs, including antiviral activity and upregulation of MHC class I antigen expression. The three proteins signal through the same heterodimeric receptor complex that is composed of the IL-10 receptor β (IL-10 Rβ) and a novel IL-28 receptor α (IL-28 Rα, also known as IFN-λR1). Ligand binding to the receptor complex induces Jak kinase activation and STAT1 and STAT2 tyrosine phosphorylation. |
