Twinsensor is a competitive test involving two receptors in one single operation. 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.

Twinsensor tests are used with dry incubator Milkotester ET- W24. When the thermostatic device has reached the set temperature 40°, then it’s ready for test.

  1. Add 200 µl of milk samples into micro wells and mix.
  2. Incubate 3 min at 40°C.
  3. Dip one Dipstick into each micro well. Continue incubating for 3 min at 40°C.
  4. Read the colour intensities.
