MicroSnap EB is a rapid test for detection and enumeration of Enterobacteriaceae (EB) bacteria. The 2 step test uses a novel bioluminogenic test reaction that generates light when enzymes that are characteristic of EB bacteria react with specialized substrates to produce light. The light generating signal is then quantified in the EnSURE luminometer. Results are available in 6 - 8 hours, enabling MicroSnap to give results in the same working day or shift.
