IL-4 protein has an important effect on B cell activation, acting as a costimulator for DNA synthesis and promoting the expression of class II MHC molecules on resting B cells. It enhances IgE and IgG1 secretion and cell surface expression while also regulating CD23 expression on lymphocytes and monocytes. IL-4 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived IL-4 protein, expressed by HEK293 , with C-His labeled tag.
