OXOID BIOCHEMICAL IDENTIFICATION SYSTEM (O.B.I.S.) MONO
OXOID BIOCHEMICAL IDENTIFICATION SYSTEM (O.B.I.S.) MONO
Description
The Oxoid Biochemical Identification System (O.B.I.S.) mono is a rapid colourimetric test 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 on to a secondary medium, such as Tryptone Soya Agar (CM0131), for further biochemical testing.
