With the latest updates to EP 2.6.7 and USP <77>, genome copies are becoming increasingly important in PCR-based mycoplasma testing.

In our latest article, we explain the difference between CFU and genome copies, why this matters for NAT-based methods, and how suitable reference material can support method validation and routine testing.

Product Highlights

QUICK TIP

Use aerosol-filter tips: Aerosol filter tips prevent contaminants from entering the pipettes and being transferred between samples. They therefore reduce the risk of cross-contamination and help ensure reliable results in PCR and mycoplasma tests.
