Abstract
Protocol to analyze lysosomal proteolysis in astrocytes generated from iPSCs.
Steps
Coat a 96 well plate Greiner 96 well Microplates Black with gelatin 0.1% or Geltrex LDEV Free hESC Quality 5 ml Thermo Fisher Scientific Catalog #A1413302 1:100
DIssociate extracted astrocytes with 0h 5m 0s
at 25°C
300x g,25°C
Resuspend the pellet in 1mL
of astrocyte media (https://www.sciencellonline.com/astrocyte-medium.html)).
Count cells and plate 10k cell per well in 100µL
of astrocyte media.
Change the media to mature astrocyte media media in the next day.
On the 3rd day, remove the media incubate with 0h 45m 0s
Remove the media
Wash with PBS 3 times.
Add 100µL
of mature astrocyte media with vehicle or with Bafilomycin A1 100nanomolar (nM)
Proceed to image in the Incucyte® SX5 Live-Cell Analysis System for 21h 0m 0s
