Purity |
> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
Endotoxin Level |
Less than 1EU per μg by the LAL method. |
Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized Human IL15 at 2μg/ml (100μl/Well) on the plate can bind IL-15RA/IL-15 R alpha/CD215, His & Avi, Human. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
21.3 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
Target 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. |
Synonyms |
