MicroSnap™ EB is a rapid test for detection and enumeration of Enterobacteriaceae (EB) bacteria. The 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™ Touch luminometer. Depending on the required level of detection, MicroSnap™ EB is able to give results within the same day.
