Interleukin 13 (IL-13) is a single-chain glycosylated polypeptide, which belongs to the IL-13/IL-4 family. IL-13 protein is secreted by many cell types, but especially by T helper type 2 (Th2) cells. IL-13 exerts its effects through a multi-subunit receptor comprising the alpha chain of the IL-4 receptor (IL-4Rα) and at least one of two known IL-13-specific binding chains (IL-13 Rα1 and IL-13 Rα2). As a cytokine, IL-13 protein is critical in regulating inflammatory, immune responses and diseases. In addition, it inhibits the production of pro-inflammatory cytokines and chemokines, and thus down-regulates macrophage activity. IL-13 protein and antibody is more importantly implicated as a central mediator of immunoregulatory processes in various cell types.

Human Cells

A DNA sequence encoding the mature form of human IL13 (AAK53823.1) (Gly 21-Asn 132) was fused with the Fc region of human IgG1 at the N-terminus.

Human

The recombinant human Fc/IL13 chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 349 amino acids and predicts a molecular mass of 39 kDa. The apparent molecular mass of rhIL13/Fc monomer is approximately 50-55 kDa in SDS-PAGE under reducing conditions due to glycosylation.

Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL13RA2 at 8 μg/ml (100 μl/well) can bind IL13 with a linear range of 0.25-8.0 ng/ml.
