Overview

The HostDetect™ E.coli PCR DNA Quant Kit is specific for DNA from E.coli genome. The reagents utilize sequence-specific primers and TaqMan® probe to amplify the 16S ribosomal RNA gene of E.coli genomic DNA for residual host genomic identification. A primer/probe set to detect Internal Control (IC), is also included for monitoring entire process from extraction to real-time PCR. The reagents also use a dUTP/UNG carryover prevention system to avoid contamination of PCR products. For more information, contact: BioprocessQC@revvity.com

Key Highlights:

  • Quantify E.coli genomic DNA with as little as 0.03 pg per PCR reaction in < 2 hours of PCR
  • Internal control detection for process monitoring from sample extraction to PCR
  • High specificity: No cross-reactivity with unrelated DNA
  • Flexible extracted DNA input volume up to 10 µL per well
  • Scalable reaction numbers from 1 to up to 192 per kit

HostDetect™ E.coli PCR DNA Quant Kit Workflow

HostDetect-PCR-DNA-Quant-Kit


The probes for the E.coli genomic DNA and Internal Control detection are labeled with FAM and HEX/VIC fluorescent dyes, respectively, to generate target-specific signal. ROX is used for Passive Reference. Any Real-time qPCR Instruments with FAM™ and VIC®/HEX™ channels can be used with this assay.
