Abstract
Protocol for preparing cells for live-cell imaging
Troubleshooting
Preparing Astrocytes
Refer to the following protocols for astrocyte lentiviral transduction:
Plating Astrocytes
No fewer than 3 days after lentiviral transduction, and after completion of antibiotic selection, passage astrocytes into plate for imaging
Coat desired wells of a 96-well, black plate with cover-slip thickness plastic (Greiner 655096 or similar) with 0.1% gelatin
Wash astrocytes with 1x PBS
Dissociate astrocytes in a trypsin enzyme solution (TrypLE Select, Gibco 12563011). For a 6-well plate of astrocytes, use 1mL per well
Transfer dissociated cells to a falcon tube with 5mL astrocyte media (AM; ScienCell #1801)
Centrifuge at 300rcf for 3 minutes at room temperature
Resuspend the cell pellet in 1mL AM and count cells
Plate 1 x 104 cells per well of the precoated 96-well plate
Imaging Astrocytes
Approximately 3 days later, incubate the cells with a live-cell compatible nuclear dye (such as Hoechst33342 or DRAQ5) for 10 minutes
Wash the cells 1x in PBS and replace with fresh AM media
Acquire images on a microscope equipped with an incubation unit and maintain the temperature at 37°C, CO2 at 5%, and humidity at 60%
