Product Info

Tested Applications
  • Direct Binding ELISA
  • Western Blot
  • CTLL-2 Proliferation Assay
Bioactivity Typically <0.5 ng/ml (15.6 pM), measured by its dose-dependent stimulation of the proliferation of CTLL-2 cells



Authentic human cell-expression with no tag.


Formulation Phosphate buffered saline (PBS) containing 0.1% bovine serum albumin (BSA)
Molecular Weight 31 kDa predicted (12.8 kDa for IL-15 + 18.4 kDa for sIL-15Rα). Heterodimer exhibits multiple bands on reducing SDS-PAGE due to varying degrees of glycosylation; migrates to a single band at ~87 kDa, observed in Native-PAGE
Source Recombinant DNA expressed in Human Embryonic Kidney Cells (HEK293)
Purity Greater than 95% as determined by SDS-PAGE by a combination of ion exchange and size exclusion chromatography
Endotoxin < 1 EU/µg
Storage For retention of full activity store at -70°C or below and avoid repeated freeze/thaw cycles
Synonyms IL-15, IL15, sIL-15Rα
