Chip-Based Digital PCR to Detect Rare Transcript Variants Using a Nanofluidic Chip
0 Views •
2025
This video demonstrates chip-based digital PCR — a variation of the digital PCR technique that is useful in detecting rare transcript variants. The PCR reaction is partitioned into the chambers of a nanofluidic chip, each of which acts as an independent reaction. The detection of fluorescence signals from the chambers with amplified targets confirms the presence of rare transcript variants in the sample.

2024
In digital marketing, metrics are crucial for evaluating the effectiveness of strategies and understanding audience behavior. These metrics, which include traffic, engagement, financial, and revenue indicators, offer a comprehensive view of marketing performance. They help businesses make informed decisions and optimize their strategies. Traffic metrics, such as page views, measure how often a web page is loaded, providing insights into a website's reach and popularity. High page views may...
FAQs
Sampling records an analog signal at defined time intervals, while quantization assigns each measurement to a numerical level. More frequent sampling can represent changes over time with greater detail, and finer numerical levels can preserve amplitude differences more accurately. Together, these operations determine how closely the digital record reflects the original laboratory or monitoring signal.
Resolution governs the number of numerical levels available for representing measured values, whereas sampling rate determines how often those values are captured. A system may therefore preserve amplitude detail without recording rapid changes adequately, or capture frequent measurements with limited numerical precision. Selecting these characteristics depends on the type of analog measurement being processed.
The USB interface transfers the digitized measurements to a computer, where they can be processed, visualized, stored, and analyzed. This connection links an analog instrument or monitoring device with digital research workflows without requiring the measurement itself to remain in an analog format. The result is a practical pathway for computer-based handling of acquired data.
It can connect existing analog instruments or imaging and monitoring equipment to a research computer, allowing their outputs to enter digital workflows. This supports visualization, archiving, and quantitative analysis while retaining the source equipment. In medicine, that capability helps integrate older measurement systems into contemporary clinical and experimental data-handling practices.
A basic workflow begins by connecting the relevant laboratory instrument, imaging system, or monitoring equipment to the digitizer and linking the digitizer to a computer through USB. The system then samples and quantizes the incoming output before transferring it for visualization, storage, or analysis. Resolution and sampling rate should match the measurement requirements.
Digitized outputs can provide computer-accessible records of signals, images, or video for visualization and quantitative analysis. Stored data also support archiving and integration into experimental workflows, making measurements easier to review and process than when they remain only in analog form. The specific information depends on the connected instrument and the characteristics of its output.
