IL-4 Protein, Human, Recombinant (hFc)

Catalog No. TMPJ-00034
Synonyms: Lymphocyte Stimulatory Factor 1, BSF-1, Pitrakinra, IL-4, IL4, Interleukin-4, Binetrakin, B-Cell Stimulatory Factor 1

Interleukin-4 (IL-4) is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. IL-4 is 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 allergic response.

Construction Recombinant Human Interleukin-4 is produced by our Mammalian expression system and the target gene encoding His25-Ser153 is expressed with a human IgG1 Fc tag at the C-terminus.
Protein Purity Greater than 95% as determined by reducing SDS-PAGE. Greater than 95% as determined by SEC-HPLC.
Molecular Weight 40-55 KDa, reducing conditions
Endotoxin Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
Reconstitution Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 
Stability & Storage

Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

Shipping

The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
