Abstract
DNA extraction (BOMB)
Steps
Sample Collection
Add 200µL of 1mm beads to 1.5ml enppendorf tube
Add200µL of 0.5mm beads to 1.5ml enppendorf tube
Add 225µL of TE buffer to 1.5ml enppendorf tube
Add 375µL of lysis buffer to 1.5ml enppendorf tube
Add 267µL of 10M ammonium acetate to 1.5ml enppendorf tube
Collect 10-20mg of sample to 1.5ml enppendorf tube
Sample crush
Put 1.5ml eppendorf tube in mixmill for sample crush, at this condition: 30 rpm/s, for 4mins 0h 4m 0s
Centrifugation
Put 1.5ml eppendorf tube in centrifuge for centrifugation, at this condition:17.0x g,25°C
DNA purification
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 sample (lysate) from 15ml centrifuge microtube to the 1st well of 96 deep well plate
Add `400µL` of **isopropanol** to the 2nd well of 96 deep well plate
Add 300µL of 80% enthanol to the 3rd well of 96 deep well plate
Add 300µL of 80% enthanol to the 4th well of 96 deep well plate
Add 100µL of DD water to the 5th well of 96 deep well plate
Put in the automated DNA extraction machine
After the extraction is done, collect 100µL of the eluted sample as the DNA template for downstream experiments
