Sentence examples for strain contamination from inspiring English sources

Upon examination of the tree, sequences from each mother/infant pair were observed to cluster separately from every other pair, thus suggesting a lack of inter-patient or reference strain contamination.

To monitor inbreeding progress and to avoid strain contamination, the pairs whose progeny was crossed in the next generation were frequently used in a genetic analysis.

While insufficient for high resolution genotyping, these data provide a useful, inexpensive, first-pass indication of probable genotype, helping to guard against inadvertent strain contamination.

We present a simple methodology for the routine authentication of laboratory strains reared in the same space involving a combination of standardized techniques that, when applied together, provide assurance of the absence of strain contamination.

Although CFP or DsRed in the published docking lines allow positive selection of the attP site a major advantage to remedy accidental strain contaminations— they bar the possibility of using the same selectable markers for transgenesis.

Physical separation of strains and their associated rearing instruments is the simplest method to prevent inter-strain contamination.

It is important to note that deviations in phenotypic expression are not always a result of inter-strain contamination but can be caused by changes in the rearing environment, for example.

As EBSD diffraction patterns (Kikuchi bands) are formed in a region close to the sample surface (up to 50 nm depth), strain and contamination lead to the loss of the diffraction pattern contrast.

The misuse or intensive use of antibiotics can lead to the development of resistance among different bacterial strains and contamination of foodstuff, with animal and human health implications [ 20].

All strains were examined for non-algal contaminants and 66 axenic algal strains or strains with bacterial contamination only (i.e., contaminants lacking telomeres and telomerase) were used for telomere/telomerase analyses.

However, some wild-derived inbred strains have genomic contamination with classical strains [ 45] and our data reveals specific examples of this when compared with sub-sets of VRs from wild-caught mice [ 34].
