Tritium 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 کاملTritium 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 کاملA superior counting solution for water-soluble tritiated compounds.
We describe a simple liquid-scintillation solution for use with water-soluble tritiated compounds that is superior to other such systems. Its advantages include: (1) a refrigerated-type liquid scintillation spectrometer is not needed because the solution has extremely good thermal stability from 22#{176} to 75#{176}C; (2) counting efficiencies are high from pH 1-12, therefore eliminating neutra...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولMass 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...
