| BioActivity: |
Arginase activity verified in a biochemical assay: Arginase 1 (ARG1, TP304649) activity was measured in a colorimetric biochemical assay. Arginase 1 catalyzes the conversion of arginine to ornithine and urea. After incubation of the protein in a solution containing L-arginine, the reaction is stopped, and the urea concentration is measured by a chemical reaction that produces a colored product that absorbs at 430 nm. By measuring the absorbance at 430 nm and comparing to a standard, the specific activity of this preparation of ARG1 was calculated to be approximately 10U/mg.
Unit definition: 1 unit of ARG1 converts 1 µmole of L-arginine to ornithine and urea per minute at pH 9.5 and 37ºC. |
