Human IL-13Ra1 Protein (ILR-HM1R1) Summary

Product Description	Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with His 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-HM1R1) Specifications/Details

Fluorophore	Unconjugated
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 0.1 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.

	Human IL-13, No Tag (Cat. IL1-HM013) immobilized on CM5 Chip can bind Human IL-13Ra1, His Tag with an affinity constant of 0.55 uM as determined in SPR assay (Biacore T200).
	Human IL-13Ra1 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	Loaded Human IL-13, hFc Tag on ProA-Biosensor can bind Human IL-13Ra1, His Tag with an affinity constant of 1.15 µM as determined in BLI assay.
	The purity of Human IL-13Ra1 is greater than 95% as determined by SEC-HPLC.
