Final Concentration | per 10 mL | Stock | |
---|---|---|---|
Tris pH7.4 | 50mM | 500uL | 1M (pH 8.0@25oC) |
Na Deoxycholate | 0.25% | 250uL | 10% |
NP-40 | 1% | 1mL | 10% |
NaCl | 150mM | 375uL | 4M |
EDTA | 1mM | 20uL | 0.5M |
NaVO3 | 100uM | 10uL | 100mM |

Basic Protocol
- Stimulate cells if necessary
- Wash cells 2x1mL with ice cold PBS -/- and aspirate
- Add 200uL Buffer: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
