RIPA lysis Materials RIPA buffer: 50 mM Tris-HCl (pH 7.5), 1% NP-40 , 0.25% Na- deoxycholate , 100 mM NaCl , 1 mM EDTA, protease inhibitor Procedure 1. Cell harvest (scraping or trypsin -EDTA) and centrifuge at 3000 rpm for 5 min at 4 o C. 2. Cell washing once with 1 ml PBS and centrifuge again. 3. Add RIPA lysis buffer (200-300 μ l for 6 well scales ) and incubate in ice for 30 min (rocking or vortex every 10 min). 4. Centrifuge at 13000 rpm for 30 min at 4 o C. 5. Take supernatant and use it for further analysis.
