Improved Cytokines IL-15 PRO

IL 15 Pro is an IL 15 with ultra high activity obtained through precise molecular design. In the production process, the problems of poor stability and easy formation of isomers of IL 15 have been solved.The purification process does not rely on reverse-phase chromatography, and it is more stable in solution .The affinity of IL 15 Pro for the IL 15 receptor is more than 100 times higher than that of the wild type, and its ability to promote the proliferation of NK cells is 20 times higher.

EXPERIMENTAL DATA

IL 15Pro SDS PAGE and SEC HPLC purity analysis

• NR & R SDS-PAGE showed that the molecular weight of the protein was approximately 15 kDa (left), and no impurity protein was observed; SEC result showed high purity with no aggregates produced (right).

Comparison o fthe solubility between IL 15Pro and IL 15

• SPR results showed that the Kd between human CD122 (IL-15R-beta) and IL-15 Pro is 0.51 nM
