Recent data suggest that cross-contamination is still a major problem with modern cell cultures. [3] [61] The International Cell Line Authentication Committee (ICLAC) notes that many cases of cell line misidentification are the result of cross-contamination of the culture by another, faster-growing cell line. This calls into question the ...
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.

Whole Foods' Brilliant Cross-Contamination Plan. Jacob Roche, The Motley Fool. Updated July 14, 2016 at 9:50 PM.
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.
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.
Possibility of cross-contamination is low since each separation is performed on a new layer. Compared to paper, it has the advantage of faster runs, better separations, better quantitative analysis, and the choice between different adsorbents. For even better resolution and faster separation that utilizes less solvent, high-performance TLC can ...
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 ...
