*If using the Branson Sonifier 250: Set at constant cycle, output control 3 (will give output measurement of 5) and sonicate samples 10x each for 10 sec with a 20 sec recovery period between each. | *If using the Branson Sonifier 250: Set at constant cycle, output control 3 (will give output measurement of 5) and sonicate samples 10x each for 10 sec with a 20 sec recovery period between each. | ||
# Spin the sonicated mixture at 14,000 rpm in a microfuge for 15 minutes at 4°C and collect the supernatant and nano drop samples and calculate the amount needed for 25ug of chromatin. | |||
# Snap-freeze the sample in liquid nitrogen and store at -80°C, or do not freeze and continue with the immunoprecipitation steps below. | |||
