Description
The One-Step Product-Enhanced Reverse Transcriptase (PERT) Assay is a highly sensitive and quantitative method for detecting reverse transcriptase (RT) activity in biological samples, particularly in retroviral research, gene therapy, and exosome studies. This assay is designed for rapid, contamination-free detection of RT using a one-step workflow.
This assay employs FAM-based fluorescence detection, making it compatible with qPCR instruments, including the 7500 Fast System. The included PERT Sample Diluent facilitates effective viral sample preparation, enhancing accuracy and reproducibility.
Assay Workflow
1. Sample Preparation: Viral samples or exosomes are resuspended in PERT Sample Diluent.
2. Reverse Transcription & Amplification: The one-step assay simultaneously reverse transcribes RNA and amplifies DNA, enabling real-time RT activity detection.
3. Detection: Fluorescence signal from FAM-labeled probes provides quantitative RT activity measurement.
Key Features & Benefits
- Wide Sample Applicability : Compatible with cell supernatant, cell lysate, and purified reverse transcriptase solution, making it suitable for diverse research applications.
- Ultra High Sensitivity & Broad Linear Range : Capable of detecting as few as dozens of RT molecules, with a linear detection range spanning at least six orders of magnitude, ensuring precise quantification.
- Minimal Interference & Cross-Contamination Prevention : One-step sample addition minimizes variability, while the single-tube reaction setup eliminates cross-contamination risks. DNA polymerase without RT activity does not interfere with detection.
- Built-in Positive Control : Includes a reverse transcriptase positive control, allowing for easy standard curve generation and significantly reducing the likelihood of false-negative results, ensuring reliable and reproducible data.
- One-Step Protocol : Streamlined workflow for faster, contamination-free RT detection.
- Exceptional Sensitivity : Detects extremely low levels of RT with unmatched accuracy.
- Integrated Positive Control : Facilitates precise quantification and enhances data reliability.
- No Cross-Contamination : Ensures clean and reproducible results in every assay.
Applications
- Retrovirus and Lentivirus Detection : Validate virus production and monitor RT enzyme activity.
- Gene Therapy & Vaccine Development : Ensure the safety and efficiency of viral vectors.
- Exosome Research : Measure RT activity in exosomal cargo for diagnostic and biomarker studies.
- Quality Control for RT Enzymes : Assess RT purity and performance in molecular biology applications.
- Medical Diagnostics : Detection of reverse transcriptase contamination in drug formulations.
- Industrial Production : Quality inspection of reverse transcriptase enzyme manufacturing.
- Cell Culture Research : Detection of RT activity in cultured cells to monitor potential contamination.
- Food Safety & Inspection : Screening for reverse transcriptase contamination in food products.
