Human melanoma cell line A375 was stained with Ultra-LEAF™ Purified CD213a2 (clone 47) (filled histogram) or LEAF™ Purified mouse IgG1, κ isotype control (open black histogram) followed by anti-mouse IgG-FITC. The staining was completely blocked by pre-incubation of the cells with recombinant human IL-13 (open red histogram).

CD213a2, also known as IL13Rα2, is a type I transmembrane protein and member of the hematopoietin family. IL13Rα2 is the high affinity receptor for IL-13, but it possibly acts as a decoy receptor to antagonize IL-13Rα1/IL-4Ra-mediated IL-13 biological functions. IL13Rα2 is expressed by fibroblasts, smooth muscle cells, keratinocytes, and activated B cells. However, its presence on the cell surface is highly regulated. CD213a2 is also expressed in various types of cancer which makes it an attractive therapeutic target.

Antibody Type
Host Species
Recombinant human IL-13R alpha 2 Fc chimera
0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/µg of the protein (<0.001 ng/µg of the protein) as determined by the LAL test.
The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. Please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF™ solution contains no preservative; handle under aseptic conditions.

FC - Quality tested
ELISA, IHC-F, Block - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per million cells in 100 µl volume or 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for relevant formats) include: ELISA1, immunohistochemistry staining of frozen tissue sections1, and blocking (competes with IL-13 for binding).

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.
