Fully functional with target cell killing

Capricorn Scientific has developed NK-Prime, a highly suitable medium for the cultivation, activation and expansion of Natural Killer (NK) cells. Expanded NK cells are fully functional with respect to killing capacity. Isolated human NK cells or PBMCs can be used as starting material.

The use of NK-Prime enables NK cells to grow by more than 50-fold within one month while maintaining all investigated properties of primary cells, such as the presence of receptors, target cell killing and degranulation activity. A 50-fold expansion rate allows for the production of 5 x 10^9 NK cells from one single buffy coat preparation.
