More Details

  • PHYTASE catalyzes the hydrolysis of phosphoester bonds on myoinositol-(1,2,3,4,5,6)-hexakisphosphate (Phytic acid or IP6) thereby releasing inositol and phosphate. Phytic acid is a major storage reservoir for phosphate in plants. Phytase is abundant in grains such as wheat and barley, and the hydrolysis of phytic acid by single-stomached animals is a crucial aspect of animal nutrition. In addition, the lack of phytase in single-stomached animals can lead to excessive phosphorus leaching into the environment due to undigested phytic acid.

    Simple, direct and automation-ready procedures for measuring phytase activity are very desirable. BioAssay Systems’ QuantiChromTM Phytase Assay is based on our Malachite Green Phosphate Assay (POMG-25H). The color intensity, measured at 620 nm, is proportionate to the amount of phosphate released from phytic acid.
