Natural Killer (NK) Cells

Get away from using irradiated feeder cells for your NK expansions. Adopt a simplified and cleaner process. Our ProDots^™ Proteins, ExCellerate^™ Media, and Cloudz^™ Cell Activation Kits are optimized for use together. We offer directly comparable RUO and GMP grades for seamless transition from research to manufacturing.

Cell Selection

• Custom GMP Antibodies for cell selection
• NK cell marker antibodies to confirm selection by flow cytometry
• Custom antibody conjugation with biotin or fluorochromes

Cytokines and Growth Factors

• GMP ProDots Proteins are formulated as dissolvable spheres enclosed inside sterile, weldable bags for closed processing cytokine addition.
• Animal-Free GMP Proteins are produced in dedicated controlled-access laboratories to prevent potential contamination by animal components or byproducts.

Small Molecules

• GMP small molecules promote somatic cell reprogramming to iPSC prior to NK cell differentiation.

   

Cell Culture Media

• ExCellerate Human NK Cell Expansion Media is serum-free and xeno-free for the expansion of CD56+ cells from human PBMCs or purified CD3+ cell-depleted PBMCs.
• Custom GMP media can be packaged in bags for direct welding into closed system processes.

Cell Expansion Kits

• Cloudz Human NK Cell Expansion Kit is based on dissolvable CD2/NKp46 microspheres for >100-fold expansion of CD3-CD56+ NK cells from PBMCs.

NK cells were expanded from human PBMCs by treatment with the Cloudz NK Cell Kit along with ExCellerate NK Cell Media and human IL-2, IL-12, IL-18, and IL-21 proteins. Cells were evaluated at Days 0, 7, 9, and 14 for fold expansion.
