Recombinant human interleukin-15 (IL-15) produced in HEK293 cells and supplied as a lyophilized, tag-free protein for research use. The preparation corresponds to residues N49-S162 of the human IL-15 sequence (accession P40933-1), is glycosylated, and is characterized for purity, endotoxin, and biological activity to support in vitro and cell culture assays. Store lyophilized at -20°C and follow recommended reconstitution and aliquoting procedures.
- Expressed in HEK293 cells for human-like post-translational modifications.
- Tag free and matches the native sequence (N49-S162).
- High purity (95% by reducing SDS-PAGE).
- Low endotoxin level (<1 EU/μg) suitable for cell-based assays.
- Verified biological activity (0.95 x 10^7 IU/mg).
- Lyophilized in PBS with 11% trehalose for enhanced stability.
- Stable frozen at -20°C; reconstitute at ≥100 μg/mL and aliquot for long-term storage.
