Evaluation of potential lactate/lactate dehydrogenase interference with an enzymatic alcohol analysis.
The Connecticut Department of Public Safety laboratory recently addressed a legal challenge to a hospital alcohol dehydrogenase (ADH)-based serum ethanol determination based on the suggestion of interference by lactate dehydrogenase (LDH)-catalyzed oxidation of lactate. Both ADH- and LDH-oxidations require NAD(+) (present in excess in the assay). NADH produced by LDH-catalyzed lactate oxidation...
متن کاملCarbon nanodots interference with lactate dehydrogenase assay in human monocyte THP-1 cells
BACKGROUND Carbon nanodots (CD), a new class of carbon nanomaterials with sizes below 10 nm, have recently attracted wide attention due to their superiority in water solubility, chemical inertness, and resistance to photobleaching. As a result, CD has found important and wide applications in energy, catalysis, biological labeling, bioimaging and drug delivery. On the other hand, due to the lack...
متن کاملLactate-to-pyruvate or pyruvate-to-lactate assay for lactate dehydrogenase: a re-examination.
The pyruvate-to-lactate assay for determining lactate dehydrogenase (EC 1.1.1.27) can now yield linearity equal to or better than that obtained by the lactate-to-pyruvate assay. In addition, there are significant advantages to the pyruvate-to-lactate reaction: (a) a greater change in absorbance per unit time, which allows more accurate spectrophotometric readout; (b) lower reactant concentratio...
متن کاملAn automated colorimetric (tetrazolium salt) assay for serum lactate dehydrogenase.
The adaptation of a tetrazolium salt assay for serum lactate dehydrogenase to full automation is described. The tetrazolium salt, INT, (2-p-iodophenyl-3-p-nitrophenyl5-phenyl tetrazolium chloride) serves as the chromogenic indicator of the enzyme activity. Phenazine methosulfate serves as an intermediate electron carrier. Estimation requires only 5 mm. of incubation, and assays may be run at th...
متن کاملMechanism of platelet interference with measurement of lactate dehydrogenase activity in plasma.
Platelets reportedly inhibit lactate dehydrogenase activity in plasma under reaction conditions of low osmolality. We describe observations inconsistent with these reports, and we attribute this "inhibition" to optical interference by platelets during the course of a reaction. We conclude that when platelet lysis is prevented and the optical interference of platelets corrected, platelet-rich pl...
