Akron’s Recombinant Human Interleukin-4 (rHu IL-4) product is manufactured following all relevant cGMP guidelines for ancillary materials. Akron’s rHu IL-4 is a single chain, 30 kDa, glycosylated cytokine analog expressed in Yeast without the use of His tags, containing 129 amino acids. The lyophilized product is packaged into vials and available in 10 µg, 30 µg, and 100 µg aliquots.
In vivo, IL-4 is a key regulator of humoral and adaptive immunity and is well known for stimulating the differentiation of T helper cells from naive T cells and stimulating the growth and differentiation of B cells. This diverse cytokine has two receptor complexes in which it interacts with; the hematopoietic receptor shares an identical subunit as the IL-2, IL-7, IL-15, and IL-21 receptor proteins, while the non-hematopoietic receptor is known to transduce IL-13 mediated signals in addition to IL-4. Akron’s cGMP-compliant rHu IL-4 can be used to promote the ex vivo activation of and class switching behavior of B cells, stimulate T helper cell differentiation, and promote the proliferation and activation of epithelial cells.
