Active Recombinant Bovine Interleukin 13

• Cat.No.: IL13-234B
• Product Overview: Recombinant Bovine IL-13 was expressed inYeast. MW= 12.6 kDa (112 aa).

Specification

• Cat. No.: IL13-234B
• Description: IL13 is an immunoregulatory cytokine produced primarily by activated Th2 cells. IL-13 is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. This gene, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL4.
