Recombinant Human IL-28A (Interleukin 28A)

Product Description:

  • Endotoxin-free
  • Animal-derived product free
  • Lyophilized and Carrier Free (CF)
  • High Activity

Xeno-free Recombinant 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).
