A radioenzymatic isotope-dilution assay for oxalate in serum or plasma.

Molecular Recognition of Biologically Relevant Anions with an Expanded Dinuclear Copper(II) Complex: An Efficient Sensor for Oxalate Anion in Aqueous Solution

“…[17] The quantitative screening of oxalate in foods and vegetables is also important for certain patients who are under follow-up of a low oxalate diet. In order to quantify the oxalate contents in the human body, different methods are clinically used; which are high performance liquid chromatography (HPLC), [18][19] capillary electrophoresis analysis (CE), [20][21] gas chromatography (GC), [22] chemiluminescence, [23] ion chromatography (IC), [24] 1 H NMR spectroscopy, [25] isotope dilution mass spectrometry, [26] and enzymatic assay. [27][28] Using a supramolecular approach, there has been an immense interest in developing efficient chemical sensors for oxalate by colorimetric and fluorescence methods.…”

Colorimetric detection of oxalate in aqueous solution by a pyrogallol red‐based Cu2+ complex

“…To date, much effort has been made to detect oxalate quantitatively by various analytical approaches including ion chromatography, high‐performance liquid chromatography, electrochemical methods, enzyme electrode assays, isotope dilution mass spectrometry and fluorescence spectroscopy . Most of these techniques require tedious sample preparation procedures, trained operators, expensive instruments and high maintenance expenditure, while colorimetric methods can offer considerable advantages over other techniques due to their simplicity, convenience, low cost, sensitivity, immediate response and naked‐eye visualization .…”
