iMediam for TiMediam for T

■ Comparison of the performance of a medium containing serum, which is currently used at our company, with “iMediam for T” (Day 14 of culture)

iMediam for T

Peripheral blood mononuclear cells (PBMC) were separated from the blood of 9 healthy individuals who gave informed consent and cultured using our medium containing serum and “iMediam for T” containing no serum to compare the cultures. The cells were cultured in OKT3 antibody-immobilized flasks until day 5 of the culture, and then were transferred to gas-permeable bags and cultured for 14 days in total. The final liquid volume was 2,000 mL.

Test protocol: iMediam for T

Day0

Container: OKT3 antibody-immobilized flask 225 Cells: PBMC from healthy individuals; 2 × 107 cells/flask (50 ml IL-2: 700 U/mL)

next
Day5

Cells are transferred to gas-permeable bags. A total of 1,000 mL

next
Day8

The number of gas-permeable bags is increased. A total of 2,000 mL

Day14

Cell number measurement, surface antigen analysis

■ Surface antigen analysis

Peripheral blood mononuclear cells (PBMC) from 3 healthy individuals who gave informed consent were cultured using “iMediam for T” containing no serum for 14 days. Then, the ratio of CD3-positive cells, which is a T-lymphocyte index, was measured by a flow cytometer. The ratio of CD3 was 98% or above in all 3 specimens, which indicates that T-lymphocytes were selectively propagated.
