IL-4  (Interleukin 4)

Product Description:

  • Endotoxin-free
  • Animal-derived product free
  • Available in Bulk
  • Higher Stability in Media
  • Authentic Glycosylation
  • Lyophilized and Carrier Free (CF)

Xeno-free IL-4 is produced in a human cell expression system with serum-free, chemically defined media. It has a demonstrated greater stability under cell culture conditions making it ideal for efficient generation of Human Dendritic Cells. (See the time saving G4 protocol available at www.HumanZyme.com).

Technical Specifications:

  • Species: Human
  • Expression: HEK293 Cell Expressed
  • Activity: Typically ≤0.6 ng/mL EC50
  • Purity: >95%
  • Endotoxin: <1 EU/µg
  • Molecular Mass: 14 and 19 kDa, monomer, 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 simulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).

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).
