Active Recombinant Human Interleukin 13, HIgG1 Fc-tagged, mutant

• Cat.No.: IL13-53H
• Product Overview: The extracellular domain of human IL-13 (AAH96139.1)(Leu25-Asn146) is fused to the N-terminus of the Fc region of a mutant human IgG1 was expressed in CHO cell.

Specification

• Species: Human
• Source: CHO
• Tag: Fc
• Protein Length: 25-146 a.a.
• Description: This gene encodes an immunoregulatory cytokine produced primarily by activated Th2 cells. This cytokine 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.
• Form: Lyophilized from 0.2μm-filtered solution in PBS.
