A Method for the Determination of Normetanephrine in Brain

Acta Physiologica Scandinavica, 1962
AbstractBrain tissue is extracted with perchloric acid. The extract is neutralized and passed through a Dowex 50 column. Elution is performed by means of a carbonate‐bicarbonate buffer, pH 10. Utilizing the principles of the trihydroxyindole method the normetanephrine of the eluate is converted into a strongly fluorescent compound.

A radioenzymatic method for determination of normetanephrine in blood plasma

Journal of Biochemical and Biophysical Methods, 1981
A radioenzymatic assay for determination of normetanephrine in blood plasma is described. It was based on N-methylation of normetanephrine by phenylethanolamine-N-methyltransferase using S-adenosyl[methyl-3]methionine as the methyl donor. 2981 +/- 85 cpm (mean +/- s mean, n = 32) were obtained from 1 ng normetanephrine. Blank values corresponded to 27 +

Individual patterns of excretion of metanephrine and normetanephrine by children

Biological Psychology, 1974
Abstract The excretion of free and conjugated metanephrine and normetanephrine by a group of children was examined for possible diurnal variations over a 48 hr period of collection. Behavioral ratings and intelligence test scores were examined for possible correlations with both the level and variability of each individual's amine excretion ...
