Intended use:

Immunoaffinity columns for use in conjunction with an HPLC or LC-MS/MS for detection of citrinin in a wide range of commodities.

General Information:

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 prior to analysis by HPLC or LC-MS/MS.


  • The immunoaffinity columns give excellent recoveries and low % RSD. High capacity and low limit of detection.
  • The columns are wide format allowing the sample to flow easily by gravity.
  • Improved clean-up and concentration of toxin from complex food matrices resulting in reduced chromatography interference and lower detection limits.

Test format 10 columns (3 ml format) (RBRDP126),
25 columns (3 ml format) (RBRP126)
Sample preparation A representative sample should be obtained by following one of the officially recognised sampling procedures. It is recommended that a minimum of 1 kg of representative sample is finely ground and a portion (10 - 50 g dependent on method used) of this is removed and extracted.
Incubation time 60 sec
LOD (Detection limit) 0.5 ng/ml (ppt)
Validated matrices

Feed and food.

Available application notes

Methods are available for all matrices covered by legislation as well as additional commodities. Please contact your local R-Biopharm distributor for further information.

Detected analyte

Citrinin in food and feed.

Evaluation It is recommended to run at least a 3 - 6 point calibration curve. In constructing a suitable curve the levels of the calibration standards should bracket or include the range of expected results. The diluted standard solutions should be prepared fresh on the day of analysis and used within a 24 hour period.
