Is XR NK Expansion Media suitable for feeder-free NK cell expansion?

XR NK Expansion Media supports NK cell expansion workflows using feeder-free cytokine-based approaches as well as feeder cell-assisted expansion systems.

Description

Expanding human natural killer (NK) cells while maintaining consistent cell quality can be challenging during immune cell research workflows. Researchers often encounter limitations including variable expansion performance, serum-related batch variation, complicated feeder cell preparation, and difficulties maintaining NK cell activity during extended culture periods.

XR NK Expansion Media is a serum-free NK cell expansion medium developed to provide a controlled culture environment for human NK cell growth, maintenance and ex vivo expansion. The optimized formulation contains essential nutrients including amino acids, vitamins and trace elements to support reliable NK cell culture performance while reducing variability associated with serum-containing systems.

Designed for modern immune cell research applications, XR NK Expansion Media is compatible with both feeder cell-based expansion approaches and feeder-free NK cell expansion workflows. The system supports NK cells derived from peripheral blood, cord blood and induced pluripotent stem cell (iPSC)-derived sources, making it suitable for diverse natural killer cell research and engineered immune cell applications.

For researchers developing CAR-NK platforms or studying NK cell immunobiology, XR NK Expansion Media provides a simplified culture workflow with reduced media preparation complexity and improved experimental consistency.
