The question remained whether incorporation of a cover crop would result in a similar restriction in timing of sampling for ISNT-N.
To identify the optimal timing of sampling for the subsequent cDNA-AFLP experiment, progress of pathogen development was followed on 'Président Roulin' and 'Gala' using light microscopy.
Other limitations of the study as a whole include the fact that there were fewer participants at the end of the study than at the beginning and that the timing of sampling for the EOS biomarker measurements and that of the rest of the data collection could have been up to 7 months apart, although 89% of samples were collected halfway through that period.
These results suggest that, both for reliability, sensitivity and for the timing of sampling, the change in proPO mRNA is more useful than the PO activity in monitoring the activation of the proPO non-specific defence system of prawns after treatment with stimulants.
The results from the model can be utilized for designing actual isotope separation setup and appropriate timing for sample collection.
Although optimization of the experimental design (timing for sample collection, transfection conditions, target concentration).
The timing for sample collection was based on a dose-response curve (supplemental material, Results S1, Figure S1) as well as previous studies [47].
Our data indicates that PBMC can be a useful source for malaria-specific memory B cells and plasma cells, but extrapolation of the results to human malaria infections suggests that timing of sampling, particularly for plasma cells, may be critical.
A frame survey divides a river or lake into various strata or zones according to ecological, fishery or social characteristics, identifies sampling locations that are typical of the various strata, and lays down a schedule for the timing of sampling.
For between subject studies the timing of sampling in relation to this cycle is an important consideration.
