Biocemical Identification System (O.B.I.S.) Pyr, Pack Of 60

Details:

Rapidly determine pyrase activity is streptococci and citrobacter spp. With thermo scientific™ oxoid™ biochemical identification system (o.B.I.S.) Pyr. This rapid colorimetric test delivers simple and rapid results for the determination of pyrase activity in streptococci and citrobacter spp, offering a rapid diagnostic alternative to time-consuming culture methods. In addition, the same enzymatic activity may be used to aid differentiation of salmonella spp. From citrobacter spp and other enterobacteriaceae1,2.Use o.B.I.S. Pyr as a rapid diagnostic alternative to time-consuming culture methods.Simple—easy to implementrapid—results in 6 minutes of testing suspect coloniesnon-carcinogenic substratesthe o.B.I.S. - Pyr test uses test cards impregnated with l-pyroglutamic acid 7-amino-4-methyl-coumarin (7amc) and dimethylaminocinnamaldehyde for the detection of pyrase activity. The enzymatic hydrolysis of this substrate by enterococci, group a streptococci and citrobacter spp. Produces a purple color following the addition of the developing solution3.We have developed a new system for pyrase testing4 using a non-carcinogenic substrate in response to health concerns associated with the use of β-naphthylamide (a potent carcinogen)5. The pyrase area on the o.B.I.S. Pyr test is impregnated with l-pyroglutamic acid 7-amino-4-methylcoumarin (7amc)4. Dimethylaminocinnamaldehyde is used as a color development reagent. The enzymatic hydrolysis of the substrate produces a purple color on addition of the o.B.I.S. Pyr developing solution4.Not all products are available for sale in all territories.
