Investigators have 90 days to tell NIAID which experiments are stopping and to propose different directions for their research.
Failure modes could not be ascertained, since the experiments were stopped due to limitations in test set-up.
All PCR experiments were stopped before fluorescence was detected in the control negative capillaries.
All experiments were stopped by ZnCO3 precipitation, and purification of the enzyme-formed cGMP was performed as described previously [33].
After 45 min incubation, BDNF (4 nM) was added for 20 min. Experiments were stopped by quick removing of the medium on ice.
Experiments were stopped at 60°C.
After 20 hours, the experiments were stopped and the diffusion setup was dismantled.
Experiments were stopped when tumor volumes reached 1 cm or earlier if necrotic.
When tumours reached a 1000-mm size the mice were killed, and for the low and non-tumorigenic cell lines the experiments were stopped after 6 months.
The osteogenic medium was changed weekly and experiments were stopped after 7, 14 or 21 days to assess the osteoblastic phenotype of MSC.
