Product Description	Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with hFc 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 / Antibody discovery / CAR-T targets

Protein	IL-13Ra1
Synonyms	IL-13 R alpha 1; IL13R; IL13RA; CT19; IL13RA1; NR4; CD213A1; AI882074
Accession	P78552
Species	Human
Biotinylated	no
Amino Acid Range	Ala27-Thr343
Molecular Weight	The protein has a predicted MW of 63.4 kDa. Due to glycosylation, the protein migrates to 75-110 kDa based on Bis-Tris PAGE result.
Activity	The affinity constant of 9.47 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-hFc
Expression System	HEK293
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 0.22um 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	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
