Description

High Precision E.coli Residual DNA Detection Kit From China

The resDNASEQ E. coli Residual DNA Quantitation Kit is a cutting-edge TaqMan™ real-time qPCR assay developed by Ducky Bio—your trusted China manufacturer of residual DNA testing reagents. Specifically engineered for quantifying femtogram-level residual E. coli DNA in biopharmaceutical products, vaccines, and cell line-based productions， this kit meets the strict sensitivity requirements defined by WHO (10 ng E. coli DNA per therapeutic dose)， making it an indispensable tool for quality control (QC) processes in GMP-compliant facilities. Whether you’re testing monoclonal antibodies, recombinant proteins, or viral vaccines， our Escherichia coli residual DNA detection kit delivers reliable, precise results to support regulatory compliance and product safety.

Rapid Results & Streamlined Workflow

1. Say goodbye to complex sample preparation and lengthy wait times. Our kit requires only 3 simple steps for sample prep (completing in just 20 minutes).

2. All components of the Sample Preparation Kit can be stored at room temperature—eliminating the need for costly cold storage and simplifying inventory management.

3.Only one reagent for qPCR MIX, and the entire test (from sample prep to results) takes just 1.5 hours—significantly boosting your QC workflow efficiency.

Exceptional Sensitivity & Accuracy

Leveraging proven TaqMan™ qPCR technology， this kit achieves a Limit of Detection (LoD) of 1 fg/μL and a Limit of Quantification (LoQ) of 5 fg/μL—enabling femtogram-level E. coli DNA detection that outperforms industry standards. With a regression coefficient of ≥0.999 for standard solutions and coefficient of variation (CV) <30% across all tested concentrations (5 fg/μL to 300 pg/μL)， it ensures consistent, trustworthy data for critical QC decisions.

The kit offers a broad linear range from 5 fg/μL to 300 pg/μL, covering the full spectrum of residual DNA concentrations encountered in bioproduction. Spiked sample tests confirm a recovery rate between 70% and 130%—ensuring accurate quantification even in complex matrices. With an amplification efficiency of 100.068%, it delivers perfect amplification curves and consistent results batch after batch.
