Immunoaffinity columns for use in conjunction with an HPLC or LC-MS/MS for detection of sterigmatocystin in a wide range of commodities.
The procedure is based on monoclonal antibody technology, which makes the test highly specific, sensitive, rapid and simple to perform. The columns contain a gel suspension of monoclonal antibody specific to the toxins of interest. Following extraction of the toxin the sample extract is filtered, diluted 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, evaporated and reconstituted prior to analysis by HPLC or LC-MS/MS.
