IL13RA2 Protein, Rat, Recombinant (Fc Tag) Product Information
> 90 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
Measured by its ability to inhibit IL13-dependent proliferation of TF-1 human erythroleukemic cells.
The ED50 for this effect is typically 0.005-0.03 μg/mL.
Protein Construction
A DNA sequence encoding the rat IL13RA2 (Q8VHK6) (Met1-Lys336) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
Expressed Host
HEK293 Cells
Predicted N Terminal
Leu 24
Molecule Mass
The recombinant rat IL13RA2/Fc is a disulfide-linked homodimer. The reduced monomer comprises 554 amino acids and has a predicted molecular mass of 63.4 kDa. The apparent molecular mass of the protein is approximately 89-93 kDa in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

IL13RA2 Background Information

Interleukin-13 receptor subunit alpha-2 (IL13RA2/IL-13RA2) is also known as also known as cluster of differentiation 213A2 (CD213A2), IL-13 receptor subunit alpha-2, IL-13R subunit alpha-2, and IL-13RA2. The IL13RA2 is often overexpressed in brain tumors, making Il13ra2 one of the vaccine targets for immunotherapy of glioma. IL13RA2/IL-13RA2 is a cancer-associated receptor that is present in greater than 80% of High Grade Astrocytomas (HGA) and has recently been recognized as a cytokine that predisposes breast cancer cells to metastasize. Expression of IL13Rα2 was rapidly lost from the surface of transduced cells grown in culture. The loss appeared to be related to ligands present in fetal bovine serum in the medium. None of the malignant glioma cell lines cultivated in vitro and tested to date exhibited the IL13Rα2 receptor. A recombinant virus (R5111) enters cells via its interaction with the IL13Rα2 receptor in a manner that cannot be differentiated from the interaction of wild-type virus with its receptors.
