Modified fluorometric method for determining plasma catecholamines.
Plasma catecholamines were fluorometrically determined by a modification of the standard alumina-trihydroxyindole method in which radioactive tracer catecholamines are used to follow the chromatographic behavior of the endogenous catecholamines on alumina. This modification permits appropriate fluorometry of that portion of the eluate with the highest concentration of catecholamines, because in...
متن کاملA Fluorometric Method for Determining the Riboflavin Content of Foodstuffs
A number of chemical methods have been described for the determination of riboflavin (1-13). These methods are in general limited in use because, when applied to certain products, either they are not specific for riboflavin or all the riboflavin present is not recovered (2). In most cases the authors of papers presenting riboflavin methods have indicated that the methods are of limited applicat...

متن کاملFluorometric procedure for determining "lamellar body" phospholipids in the particulate fraction of amniotic fluid after filtration.
A rapid (30-min) semiautomated continuous-flow procedure is described for use in assessing the phospholipids of the particulate ("lamellar body") fraction of human amniotic fluid. The method is based on measuring the difference in fluorescence of 1,6,-diphenyl-1,3,5-hexatriene added to amniotic fluid before and after micropore filtration. The filtration step removes "lamellar body" particles, w...
متن کاملManual fluorometric paper disc method for determining tyrosine in blood.
A spectrophotofluorometric method is described for the determination of tyrosine in blood dried on filter paper discs. It has been found that by immersing the paper disc containing the dried blood in aqueoustrichioracetic acid, the blood proteins remain bound to the paper and the amino acid is eluted into the aqueousphase.This method of assay is based on the principle that tyrosine reacts with ...
