Cell-based immunotherapy is at the forefront of cancer treatment. The most common type of cell-based immunotherapy to date is T-cell therapy (with CAR-T and TIL being the mainstream). The cells used in immunotherapy are generally cultured in a medium supplemented with human serum. The use of serum introduces variability in the process due to individual differences among donors, leading to inconsistencies in cell growth and characteristics. By removing this serum and simplifying the process, regulatory risks are reduced, and the associated logistical burdens are alleviated. Nutri-T eliminates the need for serum by replacing its essential components with specific proteins, lipids, and other small molecules. <Product Overview> ■ Xeno-free ■ Serum-free, no serum supplementation required ■ Compliant with ISO13408 ■ For research use only ■ Developed using cells from actual cancer patients ■ Excellent results with PBMC, TIL, and CAR-T ■ Outstanding results at low initial seeding density
