Description

Jnmedsys Clarity Plus Digital PCR Technology

Unlocking Unprecedented Precision and Sensitivity in Nucleic Acid Quantification.

Introduction

In the evolving landscape of molecular diagnostics and research, the demand for highly sensitive, accurate, and absolute quantification of nucleic acids is paramount. Traditional real-time PCR (qPCR) often relies on standard curves and can struggle with low-abundance targets, inhibitors, and minor allele detection.

The Jnmedsys Clarity Plus Digital PCR (dPCR) Technology emerges as a next-generation solution, transcending the limitations of conventional methods. By leveraging advanced microfluidics and partitioning technology, Clarity Plus offers absolute quantification of target DNA or RNA molecules without the need for a standard curve, delivering unparalleled sensitivity, precision, and robustness for a wide array of applications.

Key Features & Benefits

• Absolute Quantification:
  • Benefit: Directly count individual target molecules, eliminating the need for standard curves and reducing variability associated with reference genes.
  • Feature: Precise partitioning of samples into thousands of individual reaction chambers (droplets or wells) for endpoint analysis.
• Unrivaled Sensitivity & Specificity:
  • Benefit: Detect extremely rare mutations, low-copy number targets, and subtle variations even within complex backgrounds. Ideal for liquid biopsy, pathogen detection, and minimal residual disease (MRD) monitoring.
  • Feature: Each reaction partition acts as a separate PCR, maximizing signal-to-noise ratio and enabling the detection of single target molecules.
• Exceptional Precision & Reproducibility:
  • Benefit: Achieve highly consistent and reliable results, critical for quantitative applications and clinical diagnostics.
  • Feature: Stochastic distribution of target molecules ensures robust statistical analysis and highly reproducible data across runs and instruments.
• Robust Performance Against Inhibitors:
  • Benefit: Less susceptible to the effects of PCR inhibitors commonly found in challenging sample types (e.g., blood, tissue, environmental samples).
  • Feature: Dilution of inhibitors across thousands of partitions minimizes their impact on overall reaction efficiency.
• Multiplexing Capability:
  • Benefit: Simultaneously quantify multiple targets in a single reaction, saving sample, time, and reagents.
  • Feature: Up to X (e.g., 4 or 5) independent fluorescence channels allow for concurrent detection of different targets or probes.
• Intuitive Workflow & User-Friendly Software:
  • Benefit: Streamlined operation and easy data interpretation, reducing training time and potential for user error.
  • Feature: Guided assay setup, automated data acquisition, and comprehensive analysis software for clear, actionable insights.
• Broad Dynamic Range:
  • Benefit: Quantify targets across a wide range of concentrations, from single copies to high abundance.
  • Feature: Efficient partitioning strategy and robust chemistry allow for detection across 5-6 orders of magnitude.

How Clarity Plus Works

The Clarity Plus system functions by precisely partitioning a single PCR reaction mix (containing sample, primers, probe, and master mix) into thousands or even millions of discrete, identically sized micro-reactions. For example, in a droplet-based system, these are tiny water-in-oil emulsion droplets.

Within each partition, an individual PCR amplification either occurs (if a target molecule is present) or does not (if absent). After thermocycling, each partition is analyzed for fluorescence. Partitions that contain amplified target molecules will fluoresce, while those without will not.

The Clarity Plus software then counts the number of positive and negative partitions. Using Poisson statistics, it calculates the absolute initial concentration of the target nucleic acid in the original sample, providing a digital readout (copies/µL).

Broad Applications

The unparalleled sensitivity and precision of Jnmedsys Clarity Plus dPCR make it indispensable for a wide range of applications:

• Oncology:
  • Liquid Biopsy for circulating tumor DNA (ctDNA) detection and quantification.
  • Minimal Residual Disease (MRD) monitoring post-treatment.
  • Early cancer detection and prognosis.
  • Biomarker discovery and validation.
• Infectious Disease:
  • Ultra-sensitive pathogen detection (viral, bacterial, fungal).
  • Viral load quantification (e.g., HIV, HBV, HCV, CMV).
  • Antibiotic resistance gene detection.
• Gene Editing & Therapy:
  • Precise quantification of gene-edited alleles (e.g., CRISPR/Cas9 efficiency).
  • Quantification of viral vectors (AAV, lentivirus) for gene therapy.
• Copy Number Variation (CNV) Analysis:
  • Accurate detection and quantification of CNVs for genetic disorders.
• Non-Invasive Prenatal Testing (NIPT):
  • Detection of fetal aneuploidies from maternal plasma.
• Environmental Monitoring & Food Safety:
  • Quantification of pathogens or specific DNA in complex environmental samples.
  • Detection of genetically modified organisms (GMOs).
• Basic Research:
  • Gene expression analysis of low-abundance transcripts.
  • Epigenetic studies (e.g., methylation analysis).
  • Rare allele detection in genetic studies.
