A reverse double-isotope enzymatic histamine assay: advantages over single-isotope methods.
High concentrations of codeine necessary to demonstrate histamine release frog leukocytes interfere with histamine methylation, producing a concentration-dependent flattening of the histamine standard curves obtained from single-isotope (3H) assays . For this reason, the use of uniformly labeled l4C-histamine was investigated as as internal standard . This isotope serves as as internal standard...
متن کاملA Sensitive Double-Isotope Derivative Assay
A sensitive and specific double-isotope dilution method for assaying norepinephrine and epinephrine separately is described. The method is based on enzymatic conversion of these two catecholamines to their respective metanephrines and was applied successfully to measurement of resting plasma concentrations of norepinephrine and epinephrine in normal subjects with the finding that norepinephrine...
متن کاملEnzymatic single-molecule kinetic isotope effects.
Ensemble-based measurements of kinetic isotope effects (KIEs) have advanced physical understanding of enzyme-catalyzed reactions, but controversies remain. KIEs are used as reporters of rate-limiting H-transfer steps, quantum mechanical tunnelling, dynamics and multiple reactive states. Single molecule (SM) enzymatic KIEs could provide new information on the physical basis of enzyme catalysis. ...
متن کاملDouble isotope derivative assay of aldosterone in biological extracts.
The selective measurement of aldosterone in biological fluids has been handicapped by the lack of specific and sensitive assays. Bioassay methods (l-4) have been limited by the variation inherent in animal response. Chemical methods (5-9) require extensive purification procedures to remove contaminants, and are therefore subject to variable recoveries of the steroid. Furthermore, the quantity o...
متن کاملNovel double-isotope technique for enzymatic assay of catecholamines, permitting high precision, sensitivity and plasma sample capacity.
1. A novel use of a double-isotope method is described which allows radioenzymatic assays to combine precision and sensitivity. 2. In the catechol O-methyltransferase assay separate portions of each plasma sample are incubated with either S-[3H]- or S-[14C]-adenosyl-L-methionine. Standards of noradrenaline and adrenaline are added to the latter portions and are thus converted into standards of ...
