  3. RIDASCREEN® β-Agonists ELISA



β-Agonists such as Clenbuterol, Salbutamol and Ractopamine shift energy intake from fat deposition to muscle formation. Therefore, β-Agonists can be used as growth promoters (‘finishers’) in animal farming. However, the use of Clenbuterol and Salbutamol is worldwide prohibited in food producing animals, with some exceptions for veterinary purposes.

R-Biopharm offers a new RIDASCREEN® β-Agonists ELISA for the detection of Clenbuterol (Specificity: 100 %) and Salbutamol (Specificity: 90 %) in various matrices. The new test has improved detection limits for urine and meat. Besides sample preparation methods for serum and feed, the test kit manual includes two new methods for liver and milk.

The new RIDASCREEN® β-Agonists (Art. No. R1704) replaces the previous test (Art. No. R1703). A new version of the RIDA® SOFT Win (1.85) is available on request.

For spiking, RIDA® β-Agonists Clenbuterol-Spiking Solution is available. For the analysis of Ractopamine, RIDASCREEN® Ractopamin is available. For more information, please contact our international sales office at
