To begin, use a mechanical TissueLyser to shake previously prepared AIR CDTA mixture at 27 hertz for two minutes, followed by 10 hertz for two hours. Next, centrifuge the mixture at 10, 000 G for 10 minutes at four degree Celsius. Transfer the supernatant to a sterile micro centrifuge tube.
Finally, add sodium hydroxide and sodium borohydride mixture to the residual pellet. After shaking and centrifuging the pellet, wash the residual pellet two to three times with distilled water. Add 30 microliters per milligram of cellulase to the pellet, then incubate the tubes in a heat block at the enzyme's optimal temperature for 16 hours.
Centrifuge the samples and store the supernatant on a rotary shaker. Centrifuge all stored extracts again at 10, 000 G for 10 minutes at four degrees Celsius.
