The phrase "a pair of isolates" is correct and usable in written English.
It can be used in contexts discussing biology, linguistics, or any field where two distinct entities or examples are being referred to as isolates.
Example: "In our study, we examined a pair of isolates to understand their unique characteristics and behaviors."
Alternatives: "two isolates" or "a duo of isolates".
Strain polymorphism was verified using a pair of isolates showing the two possible allelic states.
In Dictyostelium, both Mehdiabadi et al [ 27] and Ostrowski et al. [ 36] found a positive correlation in the degree of mixing between a pair of isolates and their genetic distance for D. purpureum and D. discoideum, respectively.
Lineage 3 of WNV is represented by a pair of isolates from mosquitoes collected in the Czech Republic border region near Rabensburg, Austria, in 1997 and 1999, which have been shown experimentally to infect only mosquitoes and mosquito cells [ 68, 83].
The 15 non-outbreak strains revealed several smaller clusters or individual patterns, among them a pair of isolates with one isolate being vanA/B-negative (UW7620) and another one being vanB-positive (UW7610), the former being obviously the susceptible progenitor of the latter isolate having acquired a vanB gene cluster.
The overall level of sequence-based variation is low, with distances between clades ranging from 159 to 254 SNPs, and a maximum of 76 SNPs (minimum = 4) separating any pair of isolates within 1 clade.
In comparison, the greatest genetic distance observed between any pair of isolates derived from cattle that had no contact with buffalo was only 2.3% (isolates CD26 versus CD17, LS9 and LS12).
In this work, we have used RNA-seq to analyze the transcriptome changes associated with CDR acquisition in a pair of clinical isolates in the human pathogen C. albicans.
The general principles of the model are described and it is tested on three different Stokes flow problems; a single isolated sphere, a pair of otherwise isolated spheres, and a single sphere in a channel.
For a pair of recently isolated warbler species, and a pair of relatively old sister species of gnatcatchers, allopatry was observed at all time periods.
Profile D comprised a pair of nonsignificant pulmonary isolates of 97% similarity.
Profile B also contained a pair of highly similar isolates (94%) of which 1 was clinically significant.
