OptiVitro® NK Cell Expansion Serum-free Basic Kit P01 has been specifically designed for the in vitro expansion of human Natural Killer (NK) cells derived from either peripheral blood mononuclear cells (PBMCs) or cord blood mononuclear cells (CB-MNCs). The kit is composed of three main components: OptiVitro® NK Cell Basal SF Medium P01, OptiVitro® NK Cell SF Medium Supplement, and OptiVitro® Cytokine III. All of these components are serum-free, xeno-free, and have been manufactured in strict compliance with GMP regulations. This Kit can be combined with OptiVitro® NK Cell Expansion Serum-free Kit P01 (NE000-N02#) to facilitate and support the expansion of NK cells in vitro.
