Product Description	Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ala27-Thr343.
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.
Product Category	Recombinant Protein

Target	IL-13Ra1
Synonyms	IL-13 R alpha 1; IL13R; IL13RA; CT19; IL13RA1; NR4; CD213A1; AI882074
Gene/Protein ID	P78552-1
Species	Human
Exact Sequence	Ala27-Thr343
Molecular Weight	The protein has a predicted MW of 37.7 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.
Activity	The affinity constant of 1uM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His
Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um 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.

	Human IL-13, His Tag immobilized on CM5 Chip can bind Human IL-13Ra1, His Tag with an affinity constant of 1uM as determined in a SPR assay (Biacore T200).
	Human IL-13Ra1 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
