Shipping of the samples from European sites is carried out using styrofoam boxes filled with dry ice and from Ghana in dry shippers filled with liquid nitrogen.
Other investigators have applied additional requirements, such as eliminating genes that show changes in expression levels with collection or shipping of the samples [ 15], although the advent of RNA stabilization tubes for blood collection may make this less of a concern in future studies.
The Norwegian health authority (Helsedirektorat) authorised both, the study and the shipping of the tissue samples from Stavanger, Norway, to Giessen, Germany.
Kits to test hair for drug use often include the price of shipping the sample to a qualified laboratory for analysis.
The use of the PAXgene™ Blood RNA System offers advantages for the shipping of blood samples by direct preservation of RNA.
Shipping of dried samples causes the fewest problems; transport is not restricted by sample size or volume, and extended shipping duration is not a risk for the samples.
RRN coordinated the coding and shipping of samples and coded the data.
The caveats of shipping samples for extraction in lieu of extracting on-site include: 1) shipping materials that could be considered "hazardous," and 2) the microbial community structure of the sample could shift during the time in transit from facility to lab, leading to erroneous results.
Future studies will have to show whether cooling at transport and enrichment can reduce the negative impact of sample processing delay and if controlled shipping of cooled samples is feasible in multi-center MM trials.
However, exosomal proteins in the samples stored at RT and 4 °C were detectable out to day seven (Fig. 3), which might permit shipping of such samples from a clinical site to a research laboratory for subsequent isolation of exosomes.
Written approval for undertaking PPR vaccination, serum sample collection and shipping of samples to PANVAC was granted by respective Ministries responsible for livestock in different regions of Somalia in 2012.
