The Samples Were Homogenized In A Ball Mill

Preparation: pooled cell pellet samples were homogenized in a mini-ball mill. Into each sample 400 ul of 40% aqueous methanol, ~270 mg of 0.7 mm zirconia beads ), And two 3mm borosilicate beads (kimble chase) was added. Samples were then homogenized for 10 minutes (at the maximum rate) and centrifuged for 10 min at 4750 rpm.
