Why Choose Cowingene Enterovirus EV71 and CoxA16 Detection Kit (Liquid)?

Enteroviruses, especially EV71 and CoxA16, are major pathogens responsible for hand, foot, and mouth disease (HFMD), which can lead to severe clinical complications in pediatric populations. Rapid and accurate detection is essential for timely treatment and outbreak control.

The Cowingene Enterovirus Detection Kit is designed to meet this clinical demand by providing a qualitative PCR-based detection system that identifies Enterovirus Universal, EV71, and CoxA16 in a single analysis.

One of the key advantages of this product is its high sensitivity detection capability, with a limit of detection (LoD) of 400 copies/mL for all three targets. This ensures reliable detection even at early stages of infection when viral load is low.

In addition, the kit is designed to significantly reduce diagnostic time compared to traditional viral culture methods, enabling healthcare professionals to make faster clinical decisions and improve patient management efficiency.

The use of real-time PCR amplification technology ensures high specificity, reducing the risk of false positives or cross-reactivity with other pathogens.

The kit is compatible with widely used real-time PCR platforms, including:

ABI 7500

Roche LightCycler 480

Bio-Rad CFX96

It supports multiple fluorescence channels such as FAM, VIC/HEX, ROX, and CY5, making it adaptable to different laboratory setups.

Stable Liquid Reagent System

The liquid formulation improves ease of use and reduces preparation time. Compared with freeze-dried systems, it provides:

Faster workflow

Simplified operation

Reduced human error

Principle and Workflow of Cowingene Enterovirus Detection Kit (Liquid)

The detection system is based on Polymerase Chain Reaction (PCR) amplification of viral RNA. The workflow is designed to ensure accuracy while maintaining operational simplicity.

Sample Collection

Validated specimen types include:

Oropharyngeal swab

Herpes fluid swab

These samples are commonly used in clinical settings for enterovirus detection.

RNA Extraction

Before amplification, viral RNA is extracted using compatible reagents such as:

Cowingene Viral DNA/RNA Column

Cowingene DNA/RNA Extraction Kit

These extraction kits ensure high purity nucleic acid preparation, which is critical for accurate PCR results.

PCR Amplification

The extracted RNA is amplified using specific primers and probes targeting Enterovirus Universal, EV71, and CoxA16. The amplification process is carried out in real-time PCR instruments, allowing continuous monitoring of fluorescence signals.

Signal Detection and Interpretation

Fluorescent signals are detected in real time, and results are interpreted based on threshold cycle (Ct) values. Positive detection indicates the presence of viral RNA in the sample.

Sensitivity and Specificity Performance of EV71 and CoxA16 Molecular Diagnostic Kit

High Sensitivity

The limit of detection for all targets is:

Enterovirus Universal: 400 copies/mL

EV71: 400 copies/mL

CoxA16: 400 copies/mL

This ensures early-stage detection, even when viral load is extremely low.

High Specificity

The kit is designed to specifically identify EV71 and CoxA16 without cross-reactivity to other common respiratory or enteric viruses. This reduces the risk of misdiagnosis and ensures clinical reliability.

Reproducibility and Stability

The reagent system is stable under strict storage conditions:

≤ -20°C storage for up to 18 months

No more than 5 freeze-thaw cycles

Stable performance after thawing for 30 minutes at room temperature

These conditions ensure consistent test results across batches.
