Trisensor test kit – 96 tests

(ß-lactam+Sulfonamide+Tetracycline)

Trisensor 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.
