Compounds and controls (20
nL) were predispensed into 1536-well plates. |
Compound transfer was performed
using an ECHO 650 acoustic dispenser (LabCyte). Compounds in doses
were dispensed to columns 5–48, and controls were dispensedto
columns 1 using 1536-well plates (catalog no. EWB010000A, Aurora Microplates). |
