medium prewarmed to 28°C. Overdilution will cause cell death. In general, maximum densities
attained by shake cultures are 5–6 × 106 cells/ml. However, at these densities the cells stop growing
triplicate shaker flasks (50 mL
volume per 125 mL flask) at a seeding density of
1.5 x 106 cells/mL. Flasks were incubated at 28 C, on an
orbital shaker at 135 rpm. Cell counts and viability were
monitored using

Immunohistochemistry: Frozen tissues
Flow Cytometry: 1:50 – 1:100 per 106 cells in 100 µL volume
Optimal working dilutions must be determined by the end user.
