To assess the significance of sampling by this approach, multiple probe microdialysis sampling was used to monitor drug absorption in the stomach.
And because RNA sequencing (RNASeq) is less expensive than genome sequencing — and VIPER requires just a single tissue sample — this approach is a tenth of the cost of genetic sequencing.
Even if the microsatellites profiles of the strains present in the samples were not known a priori as in real samples, this approach was useful to understand whether and how the S. cerevisiae population changed during the fermentation, and in observing the effects of environmental changes (also encompassing the introduction of external strains) on the composition of the populations.
As WAC-MS can be multiplexed by analysing mixtures of fragments (20 100 fragments) in one sample, this approach yields high throughput, where a whole library of e.g. >2000 fragments can be analysed quantitatively within a day.
Direct measurements of POC concentrations in oceanic waters have been used extensively to investigate these processes, but because of the time-intensive effort associated with manual collection and filtration of water samples, this approach often results in limited temporal or spatial coverage.
Recently successfully employed for the analysis of a model painting fragment and some historic paint samples, this approach offers new formidable performance in terms of spatial resolution and acquisition time [34,35].
While the manual interpretation of direct infusion or LC MS spectra may be feasible for relatively simple mixtures or a small number of samples, this approach becomes daunting when large datasets and/or complex mixtures of lipids, such as those obtained from biological samples, are characterized.
While the initial purpose of quantization is to avoid the storage of analog samples, this approach however would require the relay to store the analog samples received from T0 in the first slot, until the data from T1 is received in the second slot and the two can be added and quantized.
In contrast to resected liver tissue samples, this approach provides a more accurate in-vitro model of studying the liver specific response after a proinflammatory stimulus.
While this may bias the sample, this approach we believe is more ethical and is unlikely to be detrimental to overall validity of the study.
