A method for analysis of plasma adenosine which combines the principles of radioisotope dilution and enzymatic catalysis is presented. Plasma from venous heparinized blood containing the adenosine deaminase inhibitor 2'deoxycoformycin is mixed with a small amount of [3H]adenosine and extracted with
A new and rapid method for the determination of the excitotoxic tryptophan metabolite quinolinic acid is based on its enzymatic conversion to nicotinic acid mononucleotide and, in a second step utilizing ['H]ATP, further to ['HI deamido-NAD. Specificity of the assay is assured by using a highly puri
## Abstract This assay measures picogram quantities of catechol drugs and endogenous catecholamines in body tissues and fluids. The catechols are converted to their ^3^HβOβmethyl metabolites during incubation with ^3^HβSβadenosylmethionine and the enzyme catecholβOβmethyltransferase. The radiolabel
