Radioimmunoassay and radioenzymatic assay of a new aminoglycoside antibiotic, netilmicin.
A radioimmunoassay and a radioenzymatic assay for netilmicin, a new aminoglycoside, were developed in our laboratories to assist in the study of the pharmacology of the drug and to establish values for use in its monitoring. The assays are sensitive, precise, and rapid, giving results that correlate (r = 0.90) with each other and with those of a microbiological assay in which Klebsiella pneumon...
متن کاملA simple, solid-phase iodine-125 radioimmunoassay for theophylline.
The activity of y-glutamyltransferase (EC 2.3.2.2) is measured on the DuPont aca by an adaptation of the Szasz procedure ;-y-glutamyl-p-nitroanilide is transferred to glycylglycine, thereby releasing p-nitroaniline, which is measured at 405 nm. I have noticed low glutamyltransfer-ase activity in patients with cholestasis wherealkaline phosphate (EC 3.1.3.1) is increased, total bilirubin> 100 mg...
متن کاملPreparation of iodine-125-labeled insulin for radioimmunoassay: comparison of lactoperoxidase and chloramine-T iodination.
The enzymatic radioiodination of porcine insulin by a system consisting of lactoperoxidase, hydrogen peroxide, and Na125I was compared with a modified chloramine-T technique. Satisfactory specific activity of the labeled hormone was obtained with the enzymatic iodination, with much greater immunoreactivity and stability than after chloramine-T, besides being quite suitable for the measurement o...
متن کاملتعیین پارامترهای دوزیمتری چشمۀ براکی تراپی I-125 (مدل 6711)
زمینه و هدف: تعیین دقیق توزیع دوز در اطراف چشمه های مورد استفاده در براکی ترابی بخصوص چشمههای کم انرژی به منظور انجام طراحی درمان دقیق بسیار حائز اهمیت است. در این مطالعه پارامترهای دزیمتری چشمه I-125 مدل 6711 با روش شبیه سازی مونت کارلو محاسبه می شود. روش بررسی: با استفاده از کد شبیه سازی MCNPX (2.6.0) فانتوم همگن آبی به ابعاد30 cm3 شبیهسازی شد....
