The results obtained indicate that on-site solid-phase extraction of urine can provide a simple, accurate and reproducible sampling and analytical method for the biomonitoring of styrene in urine.
"We know little about her, and a lack of fundamental information –such as her age at death, what she did for a living, what she looked like or where in the church she was buried – coupled with no known descendants who can provide a DNA sample, make it impossible to say for certain whether one of these skeletons is that of Emma, or indeed anyone else.
However, no single school can provide a representative sample of the demographic details of all schools.
CSF in this setting can provide a direct sample of brain infection.
With approximately 14,900 transcripts represented on the array, this technology can provide a representative sample of sex differences in gene expression patterns.
While laser capture microdissection (LCM) can provide a relatively homogeneous sample by concentrating on the cell type of interest, generating enough sample for a conventional proteomic study is laborious with a minimum of 100,000 cells and a dissection time in tens of hours required for one 2D-PAGE [ 22].
Hence, the blastosol can provide a highly purified sample of embryo secretions, free from contaminants derived from the culture medium.
Thus, when sampling a population of random mutants, each sequenced plasmid provides information on about seven different barcodes and sequencing 20 to 30 plasmids can provide a sufficiently large sample size to identify barcodes that are present at high frequency.
Probe-target hybridisation arrays generally measure thousands of genes and hence can provide a wealth data per sample.
This non-destructive optical technique can provide a rapid measurement of sample biochemistry and identify variations that occur between healthy and diseased tissues.
