Glossary Term
Any method that extracts and purifies DNA from biological samples, which can include the proper handling of biological samples prior to nucleic acid isolation, the separation of DNA from the rest of the components in the samples, and the storage of the DNA isolates.
Glossary Term
A purification method in which nucleic acids bind to paramagnetic beads and are collected with a magnet through wash steps. It automates well, which is why most high-throughput extraction platforms are bead-based; compare deck footprint and sample capacity when shortlisting systems.
Glossary Term
A sequence of single-stranded RNA, that is 20-25 nucleotides in length, which is transcribed from DNA but is not translated into a protein. This nucleic acid may regulate the transcription or translation of other genes.
Glossary Term
A reaction that contains all reagents except sample nucleic acid. Amplification in the NTC signals contamination of reagents or the environment, so NTC behavior is one of the first run-validity checks in any qPCR run log.
Glossary Term
Any of various amplification and detection strategies applied to detection of virus contamination in donor blood. Specifically designed to detect recently infected individuals during the latency period before seroconversion.
Glossary Term
The sample-preparation stage that lyses cells or virions and purifies DNA/RNA before amplification. Extraction quality (yield, purity, inhibitors removed) often limits assay performance more than the PCR itself, and it defines required instruments and hands-on time in a workflow.
Glossary Term
Laboratory procedure in which single stranded nucleic acids are allowed to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. By this means the degree of sequence identity can be assessed and specific sequences detected. (From Biology-online)
Glossary Term
An enzymatic pre-treatment in nucleic-acid extraction that degrades proteins and nucleases, releasing nucleic acids from clinical material before binding, wash, and elution steps.
Glossary Term
The number of nucleotides successfully ordered from each side of a nucleic acid fragment obtained after the completion of a sequencing process.
Glossary Term
An RNA molecule that does not contain protein-coding sequence information and constitutes the majority of the cellular RNA (~80%). This nucleic acid associates with multiple proteins to form ribosomes, which are the organelles that drive mRNA-directed protein synthesis.
Glossary Term
A purification method that binds nucleic acids to a silica membrane in a spin column through centrifugation or vacuum. It is a common manual and mid-throughput format with well-understood consumable logistics, but is less automation-friendly than magnetic bead approaches.
