Description

Shiga Toxin-Producing Escherichia coli qPCR Kit is designed for the quantitative detection of its specific DNA in a real-time PCR test using hydrolysis probes. In the amplification process, Taq DNA polymerase amplifies the DNA sample via quantitative PCR using a primer-probe set that targets its specific DNA region. At each cycle of the PCR, the 5' nuclease activity of Taq DNA polymerase degrades the bound probes, releasing the quenched specific FAM signal. The increase in FAM fluorescence measures the target gene-specific DNA amplifications. At a point where the fluorescence signal is confidently detected over the background signal, a Ct value can be determined for the FAM signal. This Ct parameter can be used to evaluate relative target abundance among samples.

Application Areas

Food safety and supply-chain testing: quantitative screening of STEC in foods and ingredients (e.g., beef, dairy, fresh produce, ready‑to‑eat products) and environmental swabs to support HACCP, supplier monitoring, and contamination control.
Public health research and outbreak investigation (RUO): quantitative detection and research‑level surveillance of STEC in stool enrichment cultures, isolates, and epidemiological samples to assist source tracking and research into transmission.
Environmental and agricultural monitoring: quantification of STEC in irrigation and surface waters, wastewater, soil, and farm environments for microbial contamination assessment, risk management, and One Health studies.
