Recombinant Murine IL-4

Product Details

Catalog Number: 214-14

IL-4 is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. Produced by mast cells, T cells and bone marrow stromal cells, IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, and IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergy. Recombinant Murine IL-4 is a 13.5 kDa globular protein containing 121 amino acid residues.

Product with great consistency
We have been using this cytokine for immune cells extract from mouse spleen and bone marrow in numerous publications for the past 10 years. Great consistency!
From:  Jin | Date:  7/21/2020
Great consistent IL-4 cytokine for differentiation
We routinely use this cytokine to generate mouse CD4+ Th2 cells and for M2 macrophage polarization. The pricing and consistency of this cytokine is why we have stuck with peprotech for almost 20 years. Peprotech is our sole vendor for all cytokines.
