Table 1.

Cell-specific vector productivity of clone P/cSIN/92 taken from batch cultures grown to different cell concentrations

Culture concentration (× 106 cells/mL) Cell concentration at induction (× 106 cells/mL) Average titer (TU/cell, n = 2) SD (TU/cell)
1.63 1.0 16.5 1.9
2.74 1.0 25.7 3.5
4.06 1.0 16.8 0.3
4.60 1.0 16.9 1.1

Cultures grown to different concentrations were taken out, centrifuged and then resuspended to fresh HyCell TransFx-H medium at 1 × 106 cells/mL before induction (duplicate cultures)
