Product Description
Recombinant Human IL-13Ra2 Protein is expressed from HEK293 with His tag at the C-terminus.It contains Asp27-Leu342.
Product Background
Two type 1 membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with differing affinities. The lower affinity IL-13 binding protein, previously designated IL-13 R alpha, IL-13 R alpha ' or NR4, is now referred to as IL-13 R alpha 1. The high-affinity IL-13 binding protein, previously also designated IL-13 R or IL-13 R alpha ', is now referred to as IL-13 R alpha 2.

Molecular Weight
The protein has a predicted MW of 38.28 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
Activity
Immobilized Human IL-13, hFc Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Human IL-13Ra2, His Tag with the EC50 of 8.6ng/ml determined by ELISA. See testing image for detail.

Purity
> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Form
Lyophilized
Shipping
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
