W20208A_ULEAF_IL-13_Antibody_030422
Recombinant human IL-13 (Cat. No. 571106) (black circles) induces proliferation of human TF-1 cells. Ultra-LEAF™ purified anti-human IL-13 (clone W20208A) (purple squares) neutralizes the TF-1 cell proliferation induced by recombinant human IL-13 at 15 ng/mL in a dose-dependent manner, whereas the GoInVivo™ purified rat IgG2b, κ isotype control (Cat. No. 400666) (gray triangles) does not have the effect. ND50 range: 0.015 - 0.08 µg/mL.

Description

Human IL-13 was initially cloned from cDNA libraries of activated T cells. IL-13 is an immunoregulatory cytokine secreted predominantly by activated T(H)2 cells, and it is a key mediator in the pathogenesis of allergic inflammation. IL-13 shares many functional properties with IL-4, and they share a common receptor subunit, the alpha subunit of the IL-4 receptor (IL-4Ralpha). IL-13 mediates its effects by interacting with a complex receptor system comprised of IL-4Ralpha and two IL-13 binding proteins, IL-13Ralpha1 and IL-13Ralpha2. Ligation of the IL-13 receptor complex results in signaling via the insulin receptor substrate (IRS)-1 and 2 and STAT-6 pathways. IL-13, like IL-4, is a cytokine produced by T(H)2 type helper T cells in response to signaling through the T cell antigen receptor and by mast cells and basophils upon cross-linkage of the high-affinity receptor for immunoglobulin E (IgE). IL-13 has been implicated in airway hypersensitivity and mucus hypersecretion, inflammatory bowel disease, and parasitic nematode expulsion.

Antigen Details

Structure
Cytokine
Distribution

IL-13 is secreted by activated T cells, Th2 cells, basophils, mast cells, activated eosinophils and NK cells.

Function
IL-13 modulates human monocytes/macrophages and B cells. IL-13 induces an increase of MHC class II expression in human monocytes/macrophages, and direct inhibition of inflammatory cytokines such as TNF-α and IL-1β
Interaction
IL-13 receptors are expressed on human B cells, basophils, eosinophils, mast cells, endothelial cells, fibroblasts, monocytes, macrophages, respiratory epithelial cells, and smooth muscle cells.
Ligand/Receptor
IL-4Ralpha, IL-13Ralpha1, and IL-13Ralpha2

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
