NGS basics

DNA Fluorescent Dye

A DNA fluorescent dye is a compound that binds DNA and emits measurable light, making amplification visible while it happens.

What is a DNA fluorescent dye?

Real-time monitoring depends on this signal, so anything that fluoresces without being the target product, such as primer dimers, shows up as baseline noise.

Sequencing

Sequencing is the process of reading the nucleotide order (A, T, C, G) of DNA or RNA fragments.

RNA Integrity Number (RIN)

The RNA Integrity Number (RIN) is a numerical score, from 1 to 10, used to rate the quality of an RNA sample.

Read Depth

Read depth is the total number of individual sequence reads generated for a given sample or region.

Primers

Primers are short single-stranded sequences that bind a DNA template and act as the starting point for DNA synthesis.

Polymerase Chain Reaction (PCR)

The polymerase chain reaction (PCR) is a technique that copies a specific DNA sequence exponentially through repeated temperature cycles.

Next Generation Sequencing (NGS)

Next generation sequencing (NGS) is a high-throughput technology that reads millions of DNA or RNA fragments in parallel.
