Authenticity | Verified by N-terminal and Mass Spectrometry analyses (when applicable). |
Bioactivity | The ability to increase the IL-2 proliferative effect on murine CTLL-2 cells is measured. The expected ED50 for this effect, in the presence of ≥ 1ng/ml recombinant IL-2, is between ≥ ≥ ≥ 0.5 - 1.5 µg/ml. |
Endotoxin Level | Endotoxin level is <0.1 ng/μg of protein (<1 EU/μg). |
Molecular Mass | Recombinant Human sIL-2Rαα alpha is a 24.8 kDa protein, however due to glycosylation it is observed at about 31 kDa based on SDS-PAGE and Mass Spectrometry. It consists of ≥ 219 amino acid residues, based only on the extracellular domain of IL-2R alpha. |
Protein Content | Verified by UV Spectroscopy and/or SDS-PAGE gel. |
Purity (%) | 98 |
