Microbial identification assays

qPCR assays for rapid, sensitive microbial detection

Save time spent designing primers and probes by using predesigned assay sets. The following assays have been tested on the cobas omni Utility Channel on the Roche cobas^® 6800 and 8800 Systems:

C. difficile toxin
Influenza A, B / RSV
HSV-1 / HSV-2 / VZV

Primers and probes are HPLC purified and verified by mass spectrometry, delivering batch-to-batch consistency to provide confidence in your data.
