The Phytase Assay Kit is a simple, quantitative method which can be used to measure phytase activity. Analysis is based on the hydrolysis of phytic acid by phytase and quantitative measurement of the phosphate released. Results are measured using a standard UV-VIS spectrophotometer and do not require the creation of a standard curve. The Phytase method can be used to measure phytase activity in cereal, fungal and bacterial phytases, and can also be used for the analysis of phytase in animal feed samples.
