Collect 10-20mg of sample to 2ml enppendorf tube

Put 2ml eppendorf tube in mixmill for sample crush, at this condition: 30 rpm/s, for 4mins 0h 4m 0s

Put 2ml eppendorf tube in centrifuge for centrifugation, at this condition:17.0x g,25°C

Add 350µL of isopropanol to the 1st well of 96 well plate

Add 125µL of magnetic beads (10 mg/ml) to the 1st well of 96 deep well plate

Add 200µL of the sample (lysate) from the 2ml centrifuged tube to the 1st well of 96 deep well plate
