IL13RA2 / IL13R Protein Product Information

Synonym : IL13RA2
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.

Source: Rat
Expression Host: Human Cells

IL13RA2 / IL13R Protein QC Testing

Purity: > 90% as determined by SDS-PAGE SDS-PAGE:

IL13RA2 / IL13R protein


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.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
Stability: Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N terminal: Leu 24
Molecular 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.

Formulation: Lyophilized from sterile PBS, pH7.4.
  1. Normally 5 % - 8 % trehalose and mannitol 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.

IL13RA2 / IL13R Protein Usage Guide

Storage: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

IL13RA2 / IL13R Protein Description

Interleukin-13 receptor alpha2 chain(IL-13Rα2) is one of the receptor components for IL-13, a Th2 cell-derived pleiotropic immune regulatory cytokine. IL13Rα2 contains 3 fibronectin type-III domains, and binds as a monomer with high affinity to IL-13. IL-13Rα2 exists both on the cell membrane and in soluble form intracellularly which are generated from distinct transcripts. IL-13Rα2 was initially cloned from a kidney cell line and then found to be expressed in brain, spleen, liver, thymus, and also in the bone marrow, which are hemopoietic or hypervascular tissues. Soluble IL-13Rα2 was found in multiple mouse organs and was up-regulated in lungs following allergen challenge. IL-13Rα2 is expressed on certain types of cancer cells including glioblastoma, AIDS Kaposi's sarcoma, and head and neck cancer. In a IL13Rα2 transgenic mice model, the antitumor activity of IL13-PE, a receptor-directed cytotoxin was profoundly enhanced, providing elimination of established tumor in some xenografts. Comparisons of the human and murine receptors show that they are structurally conserved, share 59% aa identity.
