Sentence examples for amplification by two from inspiring English sources

All cell samples from 11 T-cell malignancy cases exhibited clonal amplification by two out of four primer combinations.

RAE distinguishes between a "gain" of at least a single copy and an "amplification" by two or more copies.

The range of the proportion of the accessions with amplification by four other primer pairs (CW_19, LD_12, LD_29, LD_30) was 3.8 - 21.8%.

HSV-TK/ganciclovir ablations are often associated with non-specific 'bystander' killing, an apoptotic amplification by three possible mechanisms: intercellular toxin transfer via gap junctions, intercellular toxin transfer by endocytosis and/or local immunological activation by extracellular toxin.

Three more cases (4%) were negative for amplification by CISH; two of these cases contained five HER2 gene copies and one contained <5 gene copies as determined by CISH.

Li-Ning-T et al. [ 35] evaluated five invasive lobular tumors and none showed amplification by CISH, however two cases presented 2+ immunostaining.

In our study, 7 formalin-fixed samples had 2+ IHC score; three of these cases had 3+ score in parallel UMFIX section (all showed amplification by FISH) and two had 2+ score (one with amplification by FISH, Figure 2B).

Amplifications were performed by two operators in two different laboratories in order to mimic "real experimental conditions" of expression profiling.

The amplifications were aided by two different pairs of primers in separate reactions and each reaction consisted of a species specific forward primer and a universal reverse primer for strongylid species.

The transcript quantitative analysis revealed two classes of HER-2 overexpression: five cases showed a median RQ = 4.09 ± 4.33 and four of these showed gene amplification by CISH; and five other cases presented a median RQ = 2.19 ± 0.21, a value very close to the cut-off value selected (2.00).

Moreover, two samples were contaminated or confused at the amplification steps as testified by two clear-cut cases of artificial recombination.
