myo-Inositol Assay Kit

The myo-Inositol Assay Kit is a reliable and accurate enzymatic UV-method for the specific measurement and analysis of myo-inositol in animal feeds, foods and various other materials.

Phytic acid content of samples with very low levels of free myo-inositol can also be determined using K-INOSL. This can be achieved by measuring the amount of myo-inositol released after de-phosphorylation of phytic acid with the enzymes phytase and alkaline phosphatase, as used with the Megazyme Phytic Acid/Total Phosphorus Assay Kit (K-PHYT).

Not suitable for the determination of myo-inositol in baby formula.

Colourimetric method for the determination of myo-Inositol
in various sample matrices

                (myo-inositol dehydrogenase)
(1) myo-Inositol + NAD+
                   2,4,6/3,5-pentahydroxycyclohexanone + NADH + H+

(2) INT + NADH + H+ → NAD+ + INT-formazan

Kit size:    50 assays

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM 
Spectrophotometer (D-MQWAVE).
