IL-4 (Interleukin 4)
- 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).
- 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
The protein was resolved by SDS- polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue.
The activity was determined by the dose- dependent simulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).
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).
Synonyms: BCGF, BCDF, B cell stimulating factor (BSF-1) BSF1, BSF 1
