The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Endotoxin level< 0.100 Eu/µg
Additional notesThe ED50, determined by the dose-dependent stimulation of the proliferation of murine CTLL-2 cells, is < 0.5 ng/ml, corresponding to a specific activity of > 2 x 106 units/mg.

Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
FunctionCytokine that stimulates the proliferation of T-lymphocytes. Stimulation by IL-15 requires interaction of IL-15 with components of IL-2R, including IL-2R beta and probably IL-2R gamma but not IL-2R alpha.
Tissue specificityMost abundant in placenta and skeletal muscle. It is also detected in the heart, lung, liver and kidney. IL15-S21AA is preferentially expressed in tissues such as testis and thymus.
Sequence similaritiesBelongs to the IL-15/IL-21 family.
Cellular localizationSecreted and Cytoplasm. Nucleus. IL15-S21AA is not secreted, but rather is stored intracellularly, appearing in the nucleus and cytoplasmic components.
