Nuclear Physics A, 1976
Abstract Spins, parities and transition probabilities of levels in 32P at Ex > 3.5 MeV have been determined with the 29Si(α, pγ)32P reaction at bombarding energies of Eα = 12.80, 12.93 and 16.30 MeV. Proton-gamma angular correlation experiments and DSA lifetime measurements lead to six unambiguous spin assignments and to many spin limitations.

Spin-parity combinations in 32P from the 34S(, α)32P reaction
Nuclear Physics A, 1977Abstract The reaction 34S( d , α)32P has been studied using a tensor-polarized deuteron beam at bombarding energies of 8.25, 8.50, 8.75, 9.25 and 9.50 MeV. From measurement of the tensor analyzing power, T20 when α-particles are emitted near 0°, spin-parity combinations have been assigned to 23 levels in 32P in the excitation energy range 1.0 to ...

Enzymatic synthesis of [β-32P]ADP using adenylate kinase and [γ-32P]ATP
Analytical Biochemistry, 1985An enzymatic method for the synthesis of [beta-32P]ADP from [gamma-32P]ATP is described. This substrate is required for the assay of ADPase and is not commercially available. The method described results in a preparation of [beta-32P]ADP of high purity with a yield of approximately 40% the theoretical obtainable.

Synthesis of [γ-32P]thiamine triphosphate
Analytical Biochemistry, 1988We developed a novel chemical synthesis of thiamine triphosphate which allows us to incorporate 32P in the gamma position. The reaction is based on the condensation of [32P]orthophosphoric acid and thiamine diphosphate in the presence of ethyl chloroformate.

The absolute standardization of 32P and 204Tl at LNMRI
Applied Radiation and Isotopes, 200432P and 204Tl solutions were standardized within the frame of the international key comparisons organized by bureau international des poids et mesures, in 2002. The activity concentration of 32P was measured by counting solid sources in a 4pibeta proportional gas flow counter and by liquid scintillation counting.

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

Collection of Czechoslovak Chemical Communications, 1979
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.

An enzymatic method for [32P]phosphoenolpyruvate synthesis
Analytical Biochemistry, 1983Abstract A convenient method for the enzymatic synthesis of [32P]phosphoenolpyruvate from [γ-32P]ATP using partially pufified phosphoenolpyruvate carboxykinase from Escherichia coli is described. The synthesis was shown to convert essentially all the [γ-32P]ATP to [32P]phosphoenolpyruvate, which was subsequently separated from residual [γ-32P]ATP and

Metabolic studies of 32P-labelled triethylenethiophosphoramide
Biochemical Pharmacology, 1959Abstract Triethylenethiophosphoramide (ThioTEPA) labelled with radioactive phosphorus has been prepared and its metabolism examined in the rat, mouse, dog and rabbit. The drug was metabolized rapidly in vivo . The primary stage was the rapid replacement of S by O with the formation of TEPA. The mouse was exceptional in that the compound was degraded

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).
