In light of these challenges, pre-analytical methods such as end-point PCR using different reference gene amplicon lengths have been previously described to help qualify samples for molecular methods downstream [ 6- 8].
It was worth mentioning that one of the eleven local PMC samples from Hong Kong, L-PMC-11, had the highest content of THSG in all the tested samples, which was also the only one qualified sample from local pharmacy of Hong Kong.
The safety and PK analyses sets included patients who received at least one dose of sarilumab and who provided at least one qualified sample.
More than fifteen qualified samples were successfully prepared within two hour compared with even only one sample in a day for the poor manipulation accuracy of previous work.
From the scores plot, we can see intuitively a very interesting phenomenon that PMC-01, PMC-02, PMC-07, PMC-08 and L-PMC-11, which were regarded as the only five qualified samples in the present study, are separated very well with other samples in PC1.
The phenotypic characteristics of qualified samples in the two experimental populations are summarized in Table 1.
In addition, we checked the hemolysis status of all the samples and only the qualified samples were used in our study.
The StepOnePlus System (Applied Biosystems, Thermo Fisher Scientific, USA) and the Agilent 2100 Bioanaylzer (Agilent Technologies, USA) were used to quantify and qualify the sample libraries in the QC steps.
Therefore, while Fullwiley encounters scientists who, while committed to addressing health disparities and injustices in their work, seem to be somewhat less critical about the use of racial terminology to qualify their samples, Bliss (2011, 2012) claims that her interviewees are engaged, and that is the explicit reason why they adopt 'race' as a scientific parameter.
Generally, these methods requires expensive instruments, qualified personnel, sample pretreatment and are hard to use in environmental conditions.
