Product Description	Recombinant Human IL-15RA/IL-15 R alpha/CD215 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Ile31-Thr205.
Product Background	Interleukin-15 receptor alpha (IL-15R alpha) is a high affinity IL-15 binding protein that is crucial for mediating IL-15 functions such as memory CD8 T cell proliferation and NK, NK/T cell, and intestinal intraepithelial lymphocyte development.
Product Category	Recombinant Protein

Target	IL-15RA/IL-15 R alpha/CD215
Synonyms	IL-15 R alpha; CD215; IL-15RA; MGC104179
Accession	Q13261-1
Species	Human
Biotinylated	no
Amino Acid Range	Ile31-Thr205
Molecular Weight	The protein has a predicted MW of 21.3 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IL-15 at 2ug/ml (100ul/Well) on the plate. Dose response curve for Human IL-15RA, His Tag with the EC50 of 15.4ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His-Avi
Express 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	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.

	Immobilized Human IL-15 at 2ug/ml (100ul/Well) on the plate. Dose response curve for Human IL-15RA, His Tag with the EC50 of 15.4ng/ml determined by ELISA.
	Human IL-15RA on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	The purity of Human IL-15RA is greater than 95% as determined by SEC-HPLC.
