Human Residual DNA Detection Kit (qPCR), BP-QN54
qPCR kit for quantitative human host-cell DNA detection.

Product overview
Human Residual DNA Detection Kit (qPCR) is a 100-reaction BIORI qPCR kit for quantitative detection of human host-cell DNA in biological-product samples. It uses probe-based qPCR chemistry with an exogenous internal standard to monitor extraction and amplification. Human calibrators from 30 fg/µL to 300 pg/µL support residual DNA quantitation in biopharmaceutical testing workflows.

Performance data
Performance Data
Human Residual DNA Detection Kit (qPCR) Catalog No. BP-QN54-100
A product-specific validation study evaluated analytical performance for human residual DNA. This released version presents data for linear range, limit of quantitation, and recovery.
Key Performance at a Glance
| Performance parameter | Selected result |
|---|---|
| Linear range | 10 fg/μL to 300 pg/μL |
| Limit of Quantitation (LOQ) | 10 fg/μL |
| Acceptance range for recovery | 70%-130% |
Linearity
Observed in this validation study: across the evaluated range of 10 fg/μL to 300 pg/μL, the coefficient of determination (R2) was 0.9997 and the amplification efficiency was 98.467%.

Limit of Quantitation
Observed in this validation study: at 10 fg/μL, the mean concentration was 10.84 fg/μL, with 7.92% CV and 8.47% accuracy bias across 10 replicates.
