Description
Clone 47 is a monoclonal antibody that specifically recognizes the Human Interleukin-13 Receptor Subunit Alpha-2 (IL-13RA2), also known as IL-13Rα2 or CD213a2. IL-13RA2 (CD213a2) is a ~42 kDa type I transmembrane glycoprotein that is encoded by IL13RA2 which belongs to the type I cytokine receptor family. The extracellular domain is comprised of three extracellular fibronectin type III domains and a WSXWS motif that is followed by a transmembrane segment and a short cytoplasmic tail. Although this receptor primarily exists in a membrane-bound form, a soluble form may be generated upon enzymatic cleavage. IL-13RA2 (CD213a2) binds IL-13 with higher affinity than the moderate affinity IL-13RA1 (CD213a) subunit of the Type II IL-4R complex. This heterodimeric receptor complex is comprised of IL-4RA (CD124) and IL-13RA1 (CD213a) and transduces signals in response to either bound IL-4 or IL-13 ligands. IL-13RA2 (CD213a2) thus appears to act as a decoy receptor due to its short cytoplasmatic tail and lack of signaling motifs and thus controls the bioavailability and activity of IL-13. It is expressed by a subset of peripheral blood lymphocytes and immature dendritic cells. It is also known as cancer/testis antigen 19 (CT19) and may be highly expressed by a variety of malignant cells including high-grade gliomas.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
