A Sensitive Biologic Assay for ACTH

Endocrinology, 1962
Fluorometric determination of corticosteroids in adrenal venous plasma of the acutely hypophysectomized rat has led to the development of 2 new techniques for the measurement of ACTH. The first, consisting of jugular injection of test material, with adrenal venous bleeding 5 minutes later, gives linearity of response to log doses of ACTH ranging from 0.

A sensitive biological assay for interferons

Journal of Immunological Methods, 1995
Several assays are available for interferons that either measure activity (bioassays) or protein mass (ELISAs). Bioassays generally require the use of viruses and some means of determining cell killing. Many investigators lack the expertise to work with potentially harmful viral agents and eschew this approach in favor of an ELISA assay based on a ...

Assay of hypoglycin in biological samples

Analytical Biochemistry, 1978
Abstract A simple and rapid colorimetric method, applicable to extracts of biological samples, is reported for measuring the toxic amino acid l -α-amino-β-methylenecyclopropylpropionic acid (hypoglycin). By fluorimetry, as little as 10 nmol (0.14 μg) can be assayed.

Assay of hydroxyfarrerol in biological fluids

Journal of Chromatography A, 1990
A high-performance liquid chromatographic method for the determination of hydroxyfarrerol (IdB 1031) in biological samples was developed. IdB 1031 was first extracted by liquid-solid partition and the extracts were evaporated and analysed on a reversed-phase column under isocratic conditions, using either an electrochemical or a UV detector.

Automated biological assay of cholecystokinin

Medical & Biological Engineering, 1976
This paper describes a modification of the superfusion technique for the bioassay of cholecystokinin in human serum. This allows samples to be applied automatically, thus greatly increasing the number of samples, the ease of performance of the assay and its clinical significance.
