General description

Oxalic acid (Oxalate) is a strong dicarboxylic acid that occurs in several plants and vegetables. In animals, it is either incorporated from the diet or produced during ascorbic acid and glyoxylic acid metabolism. Oxalic acid is not metabolized and is excreted in the urine. Hence, it can act as a marker for glyoxylic and ascorbic acid metabolism. Furthermore, oxalic acid has been studied as a pathogenic factor for Sclerotinia sclerotiorum that inhibits the oxidative burst response in host plants. It is also known to alleviate chilling injury in peach fruit. Elevated levels of oxalic acid (oxalate) have been associated with the formation of kidney stones. Hence, oxalate measurements can be used for the diagnosis and monitoring of renal stones.


Oxalic acid colorimetric assay kit has been used in 24-hour urinary oxalate level (24HUOL) evaluation in an animal model.


Suitable for the detection of oxalate (oxalic acid) in biological samples including animal and plant tissue.


The Oxalic Acid Assay Kit provides a simple and sensitive procedure for measuring oxalic acid in variety of samples including animal and plant tissue. In this assay, oxalic acid concentration is determined by a coupled enzyme reaction, which results in a colorimetric (450 nm) product, proportional to the oxalate present.
