Immunoaffinity column for the analysis of Ochratoxin A | OCHRAPREP®

1. Intended use

The OCHRAPREP® immunoaffinity column (product code RBRP14B) is used in combination with HPLC or LC-MS/MS to detect ochratoxin A in different sample matrices, in particular coffee samples.

2. General information

- This procedure is based on monoclonal antibody technology, which gives the test high specificity and makes it sensitive, fast and simple to perform. Improved clean-up and concentration of the toxin from complex food matrices reduces chromatographic interference and lowers the detection limit. The columns contain a gel suspension of monoclonal antibodies specific to the toxin of interest. After extraction of the toxin, the sample extract is filtered, diluted and passed slowly through the immunoaffinity column. Any toxin present in the sample is retained by the antibodies in the gel suspension.

- The column is washed to remove unbound material and the toxin is then released from the column after elution with solvent. The eluate is collected before analysis by HPLC or LC-MS/MS.
