yeast for processing. To calculate the volume of culture required, use the following
equation:
(OD
600
of undiluted culture) x (culture volume in ml) = # OD•ml
For example, 3 OD•ml of yeast would require 500 µl of an undiluted culture with an
OD
600
= 6.
Note: 1 OD
600
is equivalent to approximately 8 x 10

bacterial cells/ml, or
1 x 10
7
yeast cells/ml.

* Starting material amounts in parentheses are the maximum amounts recommended for this kit. Note: The
elution volume should be decreased to 30 µl if only a small amount of starting material (<500,000 cells or
<10 mg of animal or plant tissue) is used.
** Yield figures are representative of a minimum of 20 mini column preps performed in both vacuum and spin
formats.
