Simple random samples, (using individuals as the primary sampling unit) of 1,190 and 8,000 25-year-old 25-year-old 25-year-old and 1982) weresidentsfrom the populations of three counties in Western Norway in Febornry 1997 and January-February 2007, respectinely.
By extending the previous method [ 42], we derive a general formula to estimate the proportion of contamination by normal cells for tumor cell samples using individual-level allele frequencies.
To tackle the possibility that our treatment and control groups may be sufficiently different to invalidate the DiD parallel trends assumption, we trim our sample, using individuals' treatment propensity, to construct more similar treatment and control groups.
Samples from positive pools were rerun using individual samples with the nested PCR described above.
The 18 samples were prepared separately such that gene expression analysis was performed using individual samples without pooling.
Here, we present a comprehensive proteomic profile of human platelets from ten independent platelet samples using ten individual proteomic analyses and a total of 140 1D SDS PAGE gel slices.
More importantly, gene expression changes using individual samples were statistically significant for all genes.
While SSH libraries were constructed using pooled mRNA samples, QPCR was conducted using individual RNA templates to assess biological variability.
Some DMG samples were also amplified using individual PCR reactions for each of the seven IGHV families.
