Product overview
The Ornithine Assay Kit (Fluorometric) (ab252903) provides a rapid, specific, and easy method for the measurement of total ornithine concentrations in a wide variety of biological samples. In this enzyme-based assay, ornithine is converted into a series of intermediates, which will further react with a probe producing a stable fluorometric signal (Ex/Em = 535/587nm). The kit is simple to use, sensitive and high-throughput adaptable and can detect as low as 50 pmol/well of ornithine in biological samples.

Relevance
Ornithine is one of the products of the action of the enzyme arginase on L-arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen.

Estimations of Ornithine in human serum sample (10 µL) and rat liver (62 µg protein).Estimations of Ornithine in human serum sample (10 µL) and rat liver (62 µg protein). Ornithine concentrations were 82.1 µM in human serum sample, and 14.5 pmol/µg-protein in rat liver. Assays were perfromed following the kit protocol.
