Sulfasensor Milk

   Rapid 6 minutes strip test for Sulfonamides detection

   Sulfasensor is a competitive test involving a specific antibody with high affinity for most of Sulfamide

   molecules.

   The test requires the use of two components : 

   - The first component is a microwell containing predetermined amount of antibody 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 upper red control line has to be visible after the second incubation.

  When the reagent from the microwell is re-suspended with a milk sample, specific antibodies will bind the analytes if present during

  the first incubation.

  When the dipstick is dipped into the sample, the liquid starts running vertically on the dipstick and passes through capture zones.

  When the sample is free of Sulfamides, a colour development occurs at the “test” line, indicating the absence of Sulfamides in the

  milk sample.

  On the contrary, the presence of Sulfamides in the sample will not cause the coloured signal to appear at the “test” capture line.

  How to Use  

 Benefits  

 Good to Know  

  Sulfonamides represent a class of synthetic antibacterial compounds widely used in food-producing animals for therapeutic,

  prophylactic and growth-promoting purposes.

  Improper use of sulfonamides in the dairy industry, such as excessive administration and inappropriate withdrawal period, may result

  in sulfonamide residues in milk.

  The presence of Sulfonamide residues in milk is of great concern, as they can give rise to human adverse effects (including strong

  allergic reactions, nephrotoxicity, and potential carcinogenic effect) and because they can promote growth of antibiotic-resistant strain

  of bacteria leading to inefficiency of these drugs for human therapeutic use.
