Quantity: 25 Disks/Vial, Unit Size: Each, Differentiate Staphylococcus from Micrococcus by detecting the oxidase enzyme with Thermo Scientific™ Remel™ Microdase Disk.In 1956, Kovacs^1 described the oxidase method that can be used to differentiate Gram-negative bacilli. Faller and Schleifer^2modified Kovacs' oxidase reagent by using a tetramethyl-p-phenylenediamine (TMPD) in dimethyl sulfoxide (DMSO). Tarrand and Groschel^3 further tested modified Kovacs and confirmed it to be far superior to Kov

Description

Quantity: 25 Disks/Vial
Unit Size: Each
All micrococci have cytochrome c whereas most staphylococci (with a few exceptions) lack this type of cytochrome. The oxidase reagent confirms the presence of cytochrome c^4by exhibiting color change to blue or purple.
• Ready to use: Reagent-impregnated disk. No further preparation required.
• Easy to read: Visible color change that confirms positive testPositive test: Blue or purple color development within 2 minutesNegative test: No color change (white to grey color remains) within 2 minutes.Each Microdase Disk is impregnated with tetramethyl-p-phenylenediamine (TMPD) in dimethyl sulfoxide (DMSO). The DMSO provides solubility and stability against auto-oxidation and enhances the permeability of TMPD into the bacterial cell. In presence of atmospheric oxygen, the oxidase enzyme reacts with TMPD and cytochrome c in the organism to form the colored compound indophenol.Not all products are available for sale in all territories. Please inquire.Remel™ and Oxoid™ products are now part of the Thermo Scientific brand.
