Description

Gene Amplification Instrument (TC2000-G2)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Independent Dual-Block PCR for High-Throughput Infectious Disease Testing
• Primary Use: Provides a dual-block gradient thermal cycler with two independent 48-well aluminum blocks (96 total wells), each with independent temperature control, allowing simultaneous execution of two different PCR protocols for high-throughput infectious disease detection . Features a temperature range of 0-105°C, accuracy of ±0.1°C, uniformity of ±0.2°C at 55°C, and ramp rate of 5°C/sec .

How it helps: For the clinical laboratory scientist and molecular biologist, the Gene Amplification Instrument is an independent dual-block design enables concurrent processing of different patient panels (e.g., respiratory virus panel on block 1 and bloodborne pathogen panel on block 2) without sequential runs—dramatically increasing throughput and reducing turnaround time for high-volume diagnostic laboratories . The 10.1-inch touchscreen displays real-time progress for both blocks simultaneously with visual countdown circles . For the patient, faster processing of high-volume diagnostic samples reduces turnaround time for critical test results (COVID-19, HIV, hepatitis, tuberculosis), enabling earlier diagnosis and treatment initiation.

2. Dual Independent Gradient Optimization for Assay Development
• Primary Use: Both blocks feature independent gradient temperature control (30-105°C range, 1-25°C gradient span), allowing simultaneous optimization of annealing temperatures for two different primer sets or two different PCR protocols in a single run .

How it helps: For the molecular diagnostics developer and research scientist, the ability to run independent gradient protocols on each block doubles assay development throughput—identifying optimal annealing temperatures for two primer sets simultaneously, reducing reagent consumption and shortening development time. Edge temperature compensation technology minimizes “edge effect” and enhances temperature uniformity across both blocks . For the patient, faster assay development means quicker availability of new diagnostic tests for emerging infectious diseases and genetic conditions.

3. Genetic Mutation Screening for Hereditary Disorders
• Primary Use: Used for amplification of DNA fragments from patient samples on independent blocks to detect genetic mutations associated with hereditary disorders, including β-thalassemia, sickle cell disease, cystic fibrosis, and BRCA-associated cancers, with the ability to run different screening panels concurrently .

How it helps: For the clinical geneticist and molecular pathologist in high-volume genetics laboratories, the Gene Amplification Instrument is an independent dual-block design enables rapid, reliable amplification of different gene regions simultaneously—facilitating detection of point mutations, insertions, deletions, and other genetic variants across multiple patient panels. Independent cavity design prevents cross-contamination between different sample types . For the patient undergoing hereditary disease screening, accurate PCR results inform genetic counseling, reproductive decision-making, and preventive healthcare measures.

4. Touchdown PCR for Enhanced Specificity
• Primary Use: Supports Touchdown PCR programs with a range of -10°C to +10°C (temperature increment/decrement), enabling gradual decrease of annealing temperature during cycling to enhance amplification specificity .

How it helps: For the molecular diagnostics developer and research scientist, Touchdown PCR minimizes nonspecific amplification and primer-dimer formation—critical for detecting rare mutations, low-abundance targets, and complex clinical specimens across both independent blocks . For the patient undergoing genetic testing for inherited disorders or oncology biomarkers, enhanced specificity reduces false-positive results, ensuring accurate diagnosis and appropriate treatment planning.

5. Power Failure Protection and Sample Safety
• Primary Use: Features automatic power failure protection with program recovery for both independent blocks; upon power restoration, each block automatically resumes its unfinished cycle independently, ensuring sample safety for both running protocols .

How it helps: For the clinical laboratory scientist, automatic recovery for each independent block ensures that neither patient batch is compromised during extended runs—protecting valuable clinical specimens and preventing costly re-runs. For the patient, power failure protection ensures that critical diagnostic samples are not lost due to electrical interruptions, reducing the need for repeat specimen collection.
