Tritium labeling of antisense oligonucleotides by exchange with tritiated water.
We describe a simple, efficient, procedure for labeling oligonucleotides to high specific activity (< 1 x 10(8) cpm/mumol) by hydrogen exchange with tritiated water at the C8 positions of purines in the presence of beta-mercaptoethanol, an effective radical scavenger. Approximately 90% of the starting material is recovered as intact, labeled oligonucleotide. The radiolabeled compounds are stabl...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولTritium incorporation in rats chronically exposed to tritiated food or tritiated water for three successive generations.
Wistar rats have continuously ingested tritiated food (48.1 kBq/g) or tritiated water (37.0 kBq/ml) from three weeks before mating of P0 through delivery of the F3 generation. An analysis of tissues at various ages during treatment shows that: (1) tritium incorporation into tissues of rats life-time exposed to tritiated food was on the average 3.53=0.38 times higher than after similar exposure ...
متن کاملMass Spectrometric Determinations of the Absolute Tritium Activities of NBS Tritiated Water Standards
The tritium content of U.S. National Bureau of Standards tritiated water Standard Reference Materials SRM-4926, -4926C and -4927B have been measured by mass spectrometry, where the accumulation of 3He from tritium decay is measured as a function of time. The averaged results, which are compared with other independent calibrations, are 0.7% higher than the NBS certified values and have an uncert...
