10. Mount a clean coverslip onto the slides using Vectashield

HardSet with DAPI.

11. Allow the slides to dry in the dark at room temperature for

15 min prior to imaging with a confocal microscope (see Note

4).

MTT Assay

1. Make up the MTT solution with 1 mg/mL solution of thiazo-

lyl blue tetrazolium bromide in phenol-free DMEM.

2. Carefully unclip the Alvetex® membranes and move them to a

fresh 12-well plate.

3. Wash the membranes twice with PBS.

4. Add 1 mL of the MTT solution to each well.

5. Incubate the membranes for 1 h at 37 C.

6. Aspirate the MTT solution and add 1 mL of acidified isopro-

panol to each well.

7. Place the plates on a shaker at 120 rpm for 15 min.

8. Add 180 μL of isopropanol to wells in a 96-well plate.

9. Add 20 μL of the acidified isopropanol to the wells in the

96-well plate.

10. Read the absorbance of the wells at 570 nm using a plate

reader.
