The Aflatoxin M1 plate kit is a competitive enzyme-labeled immunoassay. The Aflatoxin M1 sample extract and calibrators are pipetted into the test wells followed by the Aflatoxin M1 antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Aflatoxin M1 from the sample and Aflatoxin M1 antigen compete for binding to the Aflatoxin M1 antibody. The Aflatoxin M1 antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Aflatoxin M1 and free Aflatoxin M1 antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Aflatoxin M1 concentration of the samples is derived.

Novel method
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.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
All reagents stable for > 2 years after preparation

The Fructan Assay Kit is suitable for the specific measurement of fructan in plant extracts, animal feed and food products containing starch, sucrose and other sugars. It is used in three validated methods for the determination of fructan: AOAC method 999.03 (foods), AOAC method 2018.07 (Animal Feed) and AOAC method 2016.14 (infant formula and adult nutritionals).
New, improved procedure.
In the most recent development, a recombinant endo-levanase has been incorporated into the fructanase mixture, extending the use of the method to the measurement of levan-type fructans as are present in grasses such as timothy, cocksfoot, ryegrass and red fescue.
The method described in this booklet employs ultra-pure, recombinant enzymes and specifically measures fructans including inulin-type fructans from chicory, dahlia, jerusalem artichoke; highly branched fructans from onion and wheat stems and leaves; and levan-type fructans from pasture grasses such as timothy grass. The enzymes employed are completely devoid of contaminating enzymes active on β-glucan or gluco-oligosaccharides.
