TWINSENSOR Milk

  Rapid 6 minutes strip test for Multiple detection

  TwinSensor is a competitive test involving specific receptors with high affinity for Betalactams and

  Tetracyclines molecules.

  This convenient dipstick format makes testing easy, accurate and  economical.

  The test can be used in-situ for daily checks or in laboratories for analysis of series of milk samples.

  The test requires the use of two components :

   - The first component is a microwell containing predetermined amounts of both receptors and antibodies

      linked to gold particles.

   - The second is a dipstick made up of a set of membranes with specific capture lines.    

  Principle

  For a valid test, the red control line has to be

  visible after the second incubation.

  The ether two are the specific test lines placed   on both sides of the control line.   

  The line for B-lactam antibiotics [penicillins and

  cephalosporins] is located below the "control" while

  the line related to tetracyclines is located above it.

  When the reagent from the microwell is re-

  suspended with a milk sample, both receptors will

  bind the corresponding analytes if present during

  the first 3-minutes incubation at 40°C.

  Afterwards, when the dipstick is dipped into the

  milk, the liquid starts running vertically on the

  dipstick and passes through capture zones.

  How to Use    TwinSensor is a rapid assay in dipstick format detecting the contamination of milk samples by Betalactams and

                               Tetracyclines molecules. 

 Benefits  

 Good to Know  

  Beta-lactams and Tetracyclines antibiotics are the most widely used antibiotics for the treatment of bacterial infections in dairy cattle.

  A specific indication for administrating both antibiotic types is infectious mastitis.

  These drugs are also administered to animals in feed for growth promotion and for collective prophylactic treatment.

  The monitoring of Beta-lactams and Tetracyclines in milk is important because of the hypersensitivity of some individuals to these

  antibiotics and also because of the emergence of antibiotic-resistant strains of bacteria.

  In addition, the general residual level of antibiotics could alter the efficiency of industrial processing of raw milk toward cheese or other

  fermented dairy products preparation.

 Maximum residue limits (MRLs) have been specified for food products and milk to control the levels of these antibiotics reaching the

  consumer. The kit is available in 2 versions :

• one specific to the European Union maximum residue limits (KIT020)
• one specific to the Russian Federation (RF) milk limits (KIT034)
