Thermo Fisher, R211357, PRO Disk with Reagent

Quantity: 25 Tests/Kit
Unit Size: Each
Use PRO Kit for identification of Candida albicans and Clostridium difficile. C. albicans is the yeast pathogen most frequently isolated from clinical specimens^1. In 1990, Perry et al. evaluated a rapid test to aid in the identification of C. albicans based on colorimetric detection of the enzyme, L-proline aminopeptidase^2. C. difficile is recognized as the major cause of antibiotic-associated pseudomembranous colitis and a frequent cause of hospital-acquired diarrhoea. Fedorko and Williams reported detection of L-Proline aminopeptidase is useful for identification of C. difficile because it is one of the few biochemical tests for which this organism is positive^3.
• Easy to store- No special storage required
• Easy to read- After addition of one drop of Cinnamaldehyde a color change from red to pink color development indicates a positive testThe PRO disk contains the substrate L-proline-β-naphthylamide. This substrate is hydrolyzed by an aminopeptidase releasing β-naphthylamine. After addition of Cinnamaldehyde Reagent, β-naphthylamine reacts with ρ- dimethyl-aminocinnamaldehyde to form a red-colored complex.
