Human IL-13Ra1 Protein (ILR-HM2R1) Summary

Product Description	Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Gly22-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

Human IL-13Ra1 Protein (ILR-HM2R1) Specifications/Details

Amino Acid Range	Gly22-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 1 EU 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	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
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.
