High-efficiency liquid-scintillation counting of 14C-labelled material in aqueous solution and determination of specific activity of labelled proteins.
نویسندگان
چکیده
1. Inexpensive scintillation mixtures are described which enable the detection of as little as 40mumuc of (14)C in aqueous solution with an efficiency of counting of over 80%. 2. A rapid method for the counting of alkaline, acidic and neutral aqueous solutions of up to 1ml. volume is described. Ethanol or 2-ethoxyethanol is used as blending agent. 3. The scintillation counting of alkaline solutions is applied to the accurate determination of the specific activity of (14)C-labelled proteins from plant tissues. 4. Attention has been paid to the importance of a standardized washing procedure for the removal of all traces of radioactive material from glassware.

Determination of chemical and radiochemical purity of [14C] clozapine by high performance liquid chromatography and liquid scintillation [Persian]
Introduction: The mechanism of action and metabolism of clozapine, a complex drug used in psychopharmacology, is not completely understood. The effects of this compound in human body are related to some interactions with serotonin and dopamine neurotransmitter receptors. To further elucidate the mechanism of action and to support ongoing drug metabolism studies, [14C] clozapine with suita...

Developments of liquid-scintillation counting as a practical method for the assay of radioisotopes in biological samples followed work by Reynolds, Harrison & Salvini (1950) and Kailmann & Furst (1950). Reviews of progress and developments in liquid-scintillation counting have been given by Davidson & Fiegelson (1957) and Bell & Hayes (1958). Guinn (1958) and Stitch (1959) have reviewed the adv...
متن کاملBritain A Radiochemical Renin Assay
1. A synthetic 3-([14C]valine)-labelled tetradecapeptide renin substrate was used to measure renin concentration. Renin liberated "4C-labelled angiotensin I, which was separated from the labelled substrate by paper chromatography. The conversion ofsubstrate into angiotensin I was quantitated by liquid-scintillation counting of radioactivity. 2. The rate of conversion of the substrate into angio...
متن کاملRapid analysis method for the determination of 14C specific activity in irradiated graphite
14C is one of the limiting radionuclides used in the categorization of radioactive graphite waste; this categorization is crucial in selecting the appropriate graphite treatment/disposal method. We propose a rapid analysis method for 14C specific activity determination in small graphite samples in the 1-100 μg range. The method applies an oxidation procedure to the sample, which extracts 14C fr...
متن کاملThe assay of tritium-labelled folate in faeces by the oxygen flask combustion technique followed by liquid scintillation counting.
The assay of tritium-labelled substances in faeces requires conversion of tritium into either tritium gas (Payne and Done, 1958) or tritium-labelled water. Belcher (1961) and Kremenchuzky, Musso, Hoffbrand, and Viola (1967) used wet oxidation of faeces followed by liquid scintillation counting, while Burns and Glass (1963) used dry oxidation in a bomb calorimeter. There is a need for a reproduc...
