Glossary Term
A storage facility of biospecimens that includes tissue samples, fluids, and molecular derivatives such as DNA, RNA, and proteins. The biorepository has stringent guidelines regarding the standardized collection, handling, storage, and documentation of biological specimens.
Article
Research record from J Clin Microbiol, 2026-09-10. PMID 42721424.
Glossary Term
An ionic compound that resists changes in its pH.
Glossary Term
Enzymatic (e.g. dUTP/UNG) and physical measures that stop amplified DNA from contaminating later runs. Labs with high daily volumes usually require dUTP/UNG chemistry in purchased assays; confirm this when comparing kits from different manufacturers.
Glossary Term
Single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase.
Glossary Term
A machine that uses centrifugal force to separate heavier substances from lighter ones, for removing moisture, or for simulating gravitational effects.
Glossary Term
The nonstaining primary constriction of a chromosome which is the point of attachment of the spindle fiber; provides the mechanism of chromosome movement during cell division; the centromere divides the chromosome into two arms, and its position is constant for a specific chromosome: near one end (acrocentric), near the center (metacentric), or between (submetacentric).

Glossary Term
The genetic material of the nucleus, consisting of deoxyribonucleoprotein, which occurs in two forms during the phase between mitotic divisions: 1) as heterochromatin, seen as condensed, readily stainable clumps; 2) as euchromatin, dispersed lightly staining or nonstaining material. During mitotic division the chromatin condenses into chromosomes.
