m
g. as determined by
absorbancy at 260 nm.
One OD
260
unit is approximately 50 micrograms of Lambda DNA. Optical density ratios are used as a criterion of purity, with a typical analysis giving A
250
/A
260
= .89 at pH 7.0 and A
250
/A
260
= .52 at pH 7.0.
The viral DNA is extracted by a modification of the phenol method described by Kaiser and Hogness.
