Biochemical Identification System (O.B.I.S.) Mono

Rapidly differentiate Listeria monocytogenes from other Listeria species with Thermo Scientific™ Oxoid™ Biochemical Identification System (O.B.I.S.) mono. This rapid colorimetric test delivers simple and rapid results for the determination of D-alanyl aminopeptidase (DALAase). It has been designed for the differentiation of presumptive Listeria species that have been isolated from selective media and plated onto a secondary medium for further biochemical testing.

Identification of Listeria monocytogenes relies on the lack of the enzyme D-alanyl aminopeptidase.^1,2,3

Listeria monocytogenes is the most common pathogenic Listeria spp. and has been shown to be pathogenic to both humans and animals.

Use O.B.I.S. mono to rapidly differentiate Listeria monocytogenes from other Listeria spp., reducing the need for a full biochemical identification of suspect colonies.

• Simple—easy to implement
• Rapid—results in 6 minutes of testing suspect colonies
• Non-carcinogenic substrate

We have developed a new system for aminopeptidase testing⁴ using a non-carcinogenic substrate in response to health concerns associated with amino acid conjugates of ß naphthylamine^5,6 as these are potent carcinogens.
