    en.wikipedia.org/wiki/List_of_contaminated_cell...

    A mix-up rated as contamination could in reality be a simple confusion of two cell lines, but usually contamination is assumed. [ citation needed ] After a cell line has been discovered to be contaminated, it is usually never used again for research demanding the specific type of cell line they were assumed to be.

  4. Contamination - Wikipedia

    en.wikipedia.org/wiki/Contamination

    Within the sciences, the word "contamination" can take on a variety of subtle differences in meaning, whether the contaminant is a solid or a liquid, [3] as well as the variance of environment the contaminant is found to be in. [2] A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. [2]

  5. Genetic pollution - Wikipedia

    en.wikipedia.org/wiki/Genetic_pollution

    Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.

  6. Germ-free animal - Wikipedia

    en.wikipedia.org/wiki/Germ-free_animal

    Once a line is generated, all progeny will be germ-free unless contaminated. These progeny can then be used for experimentation. Typically for experiments, each mouse is housed separately in a sterile isolator to prevent cross-contamination between mice. The mice are provided with sterilized food and water to prevent contamination.

  7. Regenerative heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Regenerative_heat_exchanger

    The two fluid streams flow counter-current. The fluid temperatures vary across the flow area; however the local stream temperatures are not a function of time. The seals between the two streams are not perfect, so some cross contamination will occur. The allowable pressure level of a rotary regenerator is relatively low, compared to heat ...

  8. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    The latter prevents cross-contamination and stationary phase degradation due to recycling. Column chromatography can be done using gravity to move the solvent, or using compressed gas to push the solvent through the column. A thin-layer chromatograph can show how a mixture of compounds will behave when purified by column chromatography. The ...

  9. Cross-species transmission - Wikipedia

    en.wikipedia.org/wiki/Cross-species_transmission

    Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions. [2]
