Interleukin 4 (IL-4) Protein is a pleiotropic cytokine secreted primarily by mast cells, T-cells, eosinophils, and basophils that plays a role in regulating antibody production, hematopoiesis and inflammation, and the development of effector T-cell responses. IL-4 participates in STAT6 signaling and regulates the expression of MHC II, IgE, IgG1 amd CD23. IL-4 Protein, Mouse (Q136D, Y139D, sf9, His) is the recombinant mouse-derived IL-4 protein, expressed by Sf9 insect cells , with C-His labeled tag and Q136D, Y139D mutation.
Molecular Weight:
Approximately 19 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.
