Product information published by Zhuhai Biori Biotechnology Co., Ltd.
Features
- qPCR probe-based assay for conserved fungal 18S rRNA coding sequences.
- Internal control can be used to evaluate extraction efficiency or monitor amplification inhibition.
- Contains UDG enzyme to help prevent contamination from amplified products.
- Manual states a detection limit of 10 CFU/reaction when used with the specified Biori extraction or purification kit.
- COA reports conforming negative concordance, positive concordance, LOD, and internal-standard Ct results.
Application
- Qualitative fungi DNA contamination testing.
- Testing for cells, cell and gene therapy samples, and other biological products.
- qPCR workflows using supported real-time PCR systems listed in the manual.
- Sterility and microbial safety testing workflows paired with nucleic acid extraction or purification.

Study Scope and Limitations
Results apply to the two evaluated fungal organisms, non-target panel, matrices, and study conditions. This selected upload version does not make a universal fungal coverage claim. Users should verify suitability with their own organisms, sample matrix, and workflow.
