These immunoaffinity columns are designed for use in conjunction with HPLC or LC-MS/MS for detection of aflatoxin M1 in milk and dairy products.

• Can be automated for large scale analysis of samples

The procedure is based on monoclonal antibody technology, which makes the test highly specific, sensitive, rapid and simple to perform. Improved clean-up and concentration of toxins from complex food matrices results in reduced chromatography interference and lower detection limits. The columns contain a gel suspension of monoclonal antibody specific to the toxin of interest. The sample is filtered and passed slowly through the immunoaffinity column. Any toxin which is present in the sample is retained by the antibody within the gel suspension. The column is washed to remove unbound material and the toxin is then released from the column following elution with solvent. The eluate is collected prior to analysis by HPLC or LC-MS/MS.

Detection limit: LOD: 0,05 ng/ml
