Alternate Names:  B cell Stimulating Factor, BSF-1, BCDF, BCGF              
Accession Number: P07750
Description:  Interleukin 4 (IL-4) is an immunomodulatory cytokine that functions to induce naïve helper T cells to differentiate into type 2 T helper (Th2) cells. Th2 cells subsequently produce more IL-4 in a positive feedback loop. IL-4 also promotes immunoglobulin IgG to IgE isotype switching on B cells. IL-4 binds the IL-4Rα receptor to activate STAT6 signaling.
Source:  Genetically modified E.coli.
Predicted MW: Monomer, 13.7 kDa (121 aa)
Formulation:  Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 0.1% Trifluoroacetic Acid (TFA)
