A biosynthetic method for the preparation of high specific activity 32P- labeled phospholipids
WD Marggraf
32P-Labeled phospholipids with specific activities up to 400 mCi/mmole as
well as [32P]CDP-choline were prepared by cultivation of mouse fibroblasts
or mouse Ehrlich ascites cells in the presence of [32P]orthophosphate. The
method was also used to prepare [methyl- 3H]choline-labeled
glycerophospholipids from [3H]choline. The yields and the specific
activities of the phospholipids were significantly lower when preparations
of ox white blood cells were used.
