Name : Rat IL-13Ra2 Protein
Product Source :
Recombinant Rat IL-13Ra2 Protein is expressed from HEK293 with His tag at the C-terminus. It contains Leu24-Lys336.[Accession | Q8VHK6]
Molecular Weight :
The protein has a predicted MW of 37.51 kDa. Due to glycosylation, the protein migrates to 48-58 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22 μm 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Rat IL-13Ra2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Rat IL-13Ra2 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Rat IL-13Ra2, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human IL-13, hFc Tag with the EC50 of 11.7ng/ml determined by ELISA.
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.
Synonyms :
CD213a2; IL-13 R alpha 2; IL13BP; IL13R; IL13RA2; IL-13R subunit alpha-2; IL-13Ra2
