title: A rapid biosynthetic method for the preparation of radioactive phosphatidyl-CMP(CDP-diacylglycerol) of high specific activity.
abstract: A procedrue is described for the preparation of [32P]phosphatidyl-CMP(CDP-diacylglycerol) from rat pineal glands incubated with [32P]orthophosphate and DL-propranolol. The product is 95% radiopure and a high specific acitivity. The yield of liponucleotide is 0.4--0.9 micron Ci/mCi of [32P]orthophosphate in the medium. The same method can also be used for the biosynthesis and purification of [3H]phosphatidyl-CMP when [3H]cytidine is the precursor.
