Product overview
Recombinant Human IL-15RA/IL-15 R alpha/CD215 Protein is expressed in HEK293 cells with an hFc (IgG1) tag at the C-terminus. It contains amino acid residues Ile31-Thr205 (UniProt accession: Q13261-1).
Product Details
- Molecular Aliases
- IL-15 R alpha; CD215; IL-15RA; MGC104179;IL15R alpha; IL15RA
- Protein Length
- Ile31-Thr205
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 45.1 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -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.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Data Display

Immobilized Human IL-15, No Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-15RA, hFc Tag with the EC50 of 24.0ng/ml determined by ELISA (QC Test).
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.
