Rapid Enzymatic Test for Presumptive Identification of PYRase-Producing Bacteria
The Thermo Scientific™ Remel™ PYR Disc with Reagent is a rapid enzymatic test designed for the presumptive identification of enterococci, Group A streptococci (Lancefield group A), and Escherichia coli. This simple and cost-effective diagnostic test detects pyrrolidonyl arylamidase (PYRase) activity, a key enzymatic marker in differentiating these clinically significant organisms.
Available in 25, 50, and 100 test formats, the PYR Disc test is ideal for clinical laboratories requiring fast, reliable, and reproducible results.
Key Features & Benefits
- ✅ Presumptive Identification in Minutes – Detects PYRase enzyme activity within minutes
- ✅ Covers Multiple Pathogens – For Enterococcus spp., Streptococcus pyogenes (Group A), and E. coli
- ✅ Easy-to-Use Format – Each disc contains pre-impregnated substrate; just add reagent and observe color change
- ✅ Colorimetric Readout – Positive result indicated by a bright cherry-red color
- ✅ Compact & Refrigerated Storage – Requires minimal space; stored at 2°C to 8°C
- ✅ Flexible Kit Sizes – Available in 25, 50, and 100 test configurations to meet different throughput needs
