With USP <77> becoming official on October 1, now is the time to ensure your mycoplasma testing workflow meets the updated requirements. Minerva Biolabs’ redeveloped 10CFU® and 100GC® Mycoplasma Standards are ready-to-use reference materials designed for USP <77> and Ph. Eur. 2.6.7.

Precisely quantified by digital PCR, they support reliable method validation, LOD verification, and routine quality control and can be used as external positive or extraction inhibition controls.

Our residual DNA testing portfolio now covers another important host-cell system: E. coli. The new MiQuant® Residual DNA E. coli – dPCR enables absolute quantification of residual E. coli DNA directly, without prior DNA extraction.

For product-specific method validation, the dPCR Validation Standard E. coli provides quantified genomic DNA as a dedicated reference material.


One assay for routine testing. One standard for validation.
