Basic Protocol
- Stimulate cells if necessary
- Wash cells 2x1mL with ice cold PBS -/- and aspirate
- Add 200uL RIPA buffer and scrape cells
- Pipet into cold eppendorf tubes
- rotate end over end for 30 minutes at 4C to lyse
- Centrifuge 10 min at 13,000 RPM to clarify
- Transfer 150uL of lysate to fresh tube and add 150uL 2XSDS
- Load gel
