BAX® System Real-Time PCR Assay for Staphylococcus aureus

Staph aureus is a common cause of skin infections, and is known to cause foodborne illness and methycillin-resistant Staph aureus is a significant problem in clinical settings. The BAX® System Real-Time PCR assay for Staphylococcus aureus harnesses the power of the polymerase chain reaction to detect Staph aureus in food and environmental samples. The BAX® System provides everything necessary for PCR--polymerase, nucleotides and target-specific primers. The system minimizes operator handling and is easy to use. It can be used for presence/absence or threshold testing.
