B. Protein Blotting A general protocol for sample preparation. 1. Treat cells by adding fresh media containing regulator for desired time. 2. Aspirate media from cultures; wash cells with 1X PBS; aspirate. 3. Lyse cells by adding 1X SDS sample buffer (100 µl per well of 6-well plate or 500 µl for a 10 cm diameter plate). Immediately scrape the cells off the plate and transfer the extract to a microcentrifuge tube. Keep on ice. 4. Sonicate for 10–15 sec to complete cell lysis and shear DNA (to reduce sample viscosity). 5. Heat a 20 µl sample to 95–100°C for 5 min; cool on ice. 6. Microcentrifuge for 5 min. 7. Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm). NOTE: Loading of prestained molecular weight markers (#7720, 10 µl/lane) to verify electrotransfer and biotinylated protein lad- der (#7727, 10 µl/lane) to determine molecular weights are recommended. 8. Electrotransfer to nitrocellulose membrane (#12369).
