We considered the following four sources of variation: the dye incorporated into the hybridization probes (Cy5 or Cy3), sample identity (1 4), treatment (light or dark), and error due to undefined variation.
Phenotypic, metabolic and genetic properties of several Acidithiobacillus caldus strains indicate the existence of as yet undefined levels of variation within the species.
Most notably, we discovered one variation at the undefined epitope (position 3, I3L) previously identified by Shih et al. [13], and three new variations (positions of A138S, I194L, Y233H, Figure S5) without documentation in the literature.
Human rhinoviruses (HRVs) are some of the earliest identified and most commonly detected viruses associated with acute respiratory tract infections (ARTIs) and yet the molecular epidemiology and genomic variation of individual serotypes remains undefined.
The variation in the molecular profile of each individual within a group may offer a new explanation of intraspecific variation in gene expression within undefined groups of animals and provides new candidates for empirical study.
In cats, the maximum variation of the velocity is undefined.
51 Variation in other, as yet undefined genes, is suspected of modifying the expression of SCN1A mutations.
Surprisingly, the impact of genetic variation on gene regulation and the relative importance of the genetic mechanisms underlying regulatory variation in mammalian embryogenesis remain undefined.
Although it is usually considered as an industry standard, its procedure was not fully defined by Fred Bond, and sometimes sensible variations in test results can be obtained due to some undefined steps in the method.
Whilst a standardised measure for adherence remains undefined, studies continue to produce heterogeneous adherence results which may be due to variations in adherence measurement, duration of monitoring and definition of adherence.
