Product Description:
- Endotoxin-free
- Animal-derived product free
- Lyophilized and Carrier Free (CF)
- High Activity
Xeno-free human IL-28AHuXp (IFN lambda 2) is expressed in human 293 cells with an apparent molecular mass of 24 kDa. This cytokine is produced in a serum-free, chemically defined media. Production in human 293 cells offers authentic human post-translational modification which contributes to stability in cell growth media and other applications. The purity is greater than 95%.
Technical Specifications:
- Species: Human
- Expression: HEK293 Cell Expressed
- Activity: Typically ≤5 ng/mL EC50
- Purity: >95%
- Endotoxin: <1 EU/μg
- Molecular Mass: 24 kDa, monomer, non-glycosylated
- Formulation: 1x PBS
Purity Confirmation:
The protein was resolved by SDS-polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue.
Activity Assay:
The activity was determined by the dose-dependent protection of the cytopathic effect on A549 cells (human lung adenocarcinoma epithelial cell line) that were challenged with encephalomyocarditis (EMC) virus.
Reconstitution Buffer:
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 1xPBS containing 0.1% endotoxin-free recombinant human serum albumin (HSA).
