Sentence examples for spike concentrations from inspiring English sources

Therefore, there are altogether 34 unique labeled and spiked 50 mers against a human cRNA background for each of the spike concentrations.

The claimed mLR concentration response range of the tests was confirmed within reasonable limits, although the false negative and false positive rates were significant for spike concentrations below 2.5μg/LL (Recreational Strip Test).

This factor was obtained using linear regression and information about the known spike concentrations per cell.

These were tested at five different bacterial spike concentrations in triplicate per run, for four runs.

Sensitivity was only decreasing when spike concentrations were very low (cf. charts 2 – 6 in figure 4) but this was also observed with dChip or with RMA and SAM.

Significant trends in spike concentrations in sediment, water, and amphipods with time were assessed by Kruskal Wallis rank tests; specific differences in concentration between time points were determined using the Mann–Whitney rank sum statistic.

We assess individual probe performance by fitting the Langmuir isotherm to the hybridization intensity of spiked probes vs known spike concentration.
