Fluorometric ultramicrodetermination of calcium in biologic fluids.
HE PURPOSE OF THIS PAPER 5 to describe a micromethod for the fluorometric determination of calcium in blood serum, plasma, urine, and cerebrospinal fluid. The method is an adaptation of the fluorometric procedure of Wallach et al (1, 2) and Kepner and Hercules (3) to the TJnopette system* (4, s). The original procedure involved the preparation of a stock solution of Calcein or fluorescein compl...
متن کاملFluorometric measurement of fecal bile acids.
A method is described for the fluorometric determination of fecal bile acids. The method combines solvent extraction and thin-layer chromatography (TLC) isolation tech nics with a fluorometric method for measuring total bile acids. Recoveries of individual bile acids added to feces averaged 107% with a standard deviation of ± 5.6%. Bile acid excretion in normal human subjects on a self-selected...

متن کاملThe fluorometric measurement of pyridine nucleotides.
Measurement of DPNH’ or TPNH by absorption at 344 rnp has been a standard procedure for many years and has been used to study innumerable enzyme reactions. In spite of the proved value of this calorimetric method, there may be advantages in fluorometric methods for the pyridine nucleotides. First, it has been found practicable with a fluorometer to determine separately oxidized and reduced pyri...
متن کاملFluorometric measurement of creatine kinase activity.
SERUM CREATINE KINASE activity has beell measured by determining the amount of creatine liberated in the following reaction: ADI + creatine phosphate ATP + creatine. The Voges-Proskauer reactioii, production of a color by reaction of creatille with diacetyl alid -naphthol, has heeii used to measure enzymatically released creatine (1-5). The presence of a sulfhydryl compound in tile incubatioii ...
