The BactTest (TM) Gram negative detection kit is a presumptive screen intended for the rapid detection of e.coli bacteria from either a swab sample (for surface detection) or 1mL water sample (for liquid detection) using the FluoroQuik BactTest handheld fluorometer. The assay utilizes a fluorogenic substrate which, when hydrolyzed by a specific enzyme (during peptide hydrolysis), produces a fluorescence which is conveniently read by the BT-360/460-B fluorometer.
(Carrying case and fluorometer shown in the picture are not included in the assay kit and sold separately.)
