The time course of the changes of the counting rate caused by 32P is determined in six commercially available scintillation mixtures applicable to aqueous solutions of the samples. The measurements were performed separately in the 3H- and 32P-measuring channels.

A procedure for the preparation of [32P]phosphatidic acid
Analytical Biochemistry, 1986The phosphorylation procedure of F. Cramer, W. Rittersdorf, and W. Bohm [(1961) Chem. Ber. 654, 180] using bis(triethylammonium) phosphate and trichloroacetonitrile was shown to be effective in the synthesis of [32P]phosphatidic acid. From diacylglyceride and 0.5 mCi H(3)32PO4, 25-50 microCi of labeled material (sp act = 1 mCi/mumol) can be prepared in

A route for the preparation of [32P]‐sodium monofluorophosphate
Journal of Labelled Compounds and Radiopharmaceuticals, 1999[32P]-labelled sodium monofluorophosphate (Na2FPO3) was prepared according to a procedure, which is based on melting of a mixture of carrier-added [32P]-phosphoric acid and ammonium bifluoride, both solid. Monofluorophosphate was precipitated as the silver salt from the reaction mixture, then it was converted to the sodium salt by using a cation ...

False-Positive 32P Uptake Tests
Archives of Ophthalmology, 1978Three patients had suspected choroidal melanoma and positive results for radioactive phosphorus (32P) uptake tests, leading to enuclearion in two of the patients. No malignancy was present on histopathologic examination. This experience reemphasizes the need for the ophthalmologist to evaluate the total clinical picture and not to give inappropriate ...

Absorption and Translocation of Phosphate-32P
1974Terrestrial seed plants require approximately 12 mineral elements, in addition to nitrogen, which they absorb as inorganic ions through their roots from the soil. Ion absorption occurs by two basic processes commonly known as passive and active ion uptake.

32P-Postlabeling Analysis of DNA Adducts
201432P-Postlabeling analysis is an ultra-sensitive method for the detection of DNA adducts, such as those formed directly by the covalent binding of carcinogens and mutagens to bases in DNA, and other DNA lesions resulting from modification of bases by endogenous or exogenous agents (e.g., oxidative damage).

Effects of 32P decay on enzyme synthesis
Journal of Molecular Biology, 1961Cultures of Escherichia coli 15T − inactivated by 32 P decay to a survival of 0·1% are capable of synthesizing phosphatase at about 25% of the rate found in completely viable cells. These cultures also retain a similar fraction of their ability to form β -galactosidase, if no energy source is present during the induction.
