QA19A66_ULEAF_IL-4_RECOM_Antibody_101421
Recombinant mouse IL-4 (Cat. No. 574306) (black circles) induces the proliferation of HT-2 mouse cells. Ultra-LEAF™ purified anti-mouse IL-4 recombinant antibody (clone QA19A66) (purple squares) inhibits the effect of recombinant mouse IL-4 at 7 ng/mL in mouse HT-2 cells in a dose-dependent manner whereas the GoInVivo™ purified mouse IgG1, κ isotype ctrl antibody (Cat. No. 400192) (gray triangles) does not have the effect. ND50 range: 0.1 - 0.5 µg/mL

Description

IL-4 is a member of the short four-helix bundle family of cytokines. IL-4 is produced by Th2 cells in response to antigen receptor engagement. Dendritic cells can prime naïve CD4+ T cell; nevertheless, it has been described that dendritic cell mediated priming is insufficient for the development of Th2 cell-dependent immunity. Basophils have been identified as a source of IL-4 in the initial naïve CD4+ T cell priming. These cells coexpress MHC class II and IL-4 following helminth infection. Therefore, murine basophils could present antigens to naïve T cells, thus promoting Th2 cell differentiation during allergic and anti-parasitic immune responses. In addition, it was previously known that upon cross-linkage of the high affinity receptor for immunoglobulin E, IL-4 is produced by NK cells, mast cells, and basophils. Cells of hematopoietic stem cell origin express the type I receptor for IL-4 (IL-4Ra, γc), and cells of non-hematopoietic stem cell origin express type II receptor (IL-4Ra, IL-13Ra1). Type I receptor complexes are active in regulating Th2 development. In contrast, the type II receptor complex is active in regulating cells that mediate airway hypersensitivity and mucus secretion.

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.
