We undertook a pilot exploratory study comparing the enumeration of CTCs using two technology platforms (CellSearch and ISET) to assess the feasibility of CTCs as a useful source for biomarker research in this disease.
Thus in the present study we have taken the approach of using two array platforms, each possessing different probe design, synthesis and attachment strategies and different hybridization kinetics and lab procedure.
Length frequency distribution of raw reads clustered around the 200-to-300 bp and 300-to-400 bp range as the result of using two different platforms for sequencing.
Nonetheless, using two different platforms had the inherent advantage of enhanced overall transcriptome coverage.
Samples were analysed using two analytical platforms.
The efficiency of our strategy was tested by using two of the main NGS platforms available: the 454 Roche platform and MiSeq Illumina platform.
The transcriptome sequencing of the two samples was performed by using two of the main sequencing platforms available on the market: the 454 Roche platform and MiSeq Illumina platform [ 14].
The comparison and the combination effect of using two '-omics' platforms in predicting the therapeutic effects and adverse effects of particular drugs will be thoroughly evaluated in follow-up research.
Each amplicon pool was purified using the Mobio UltraClean PCR Clean-up kit (Mo Bio laboratories, Carlsbad, CA, USA) and sequenced using two lanes of the Illumina HiSeq sequencing platform at the BioFrontiers Institute Next-Generation Genomics Fatility at University of Colorado, Boulder.
The potential weakness of using two different genotyping platforms for case and comparison subjects has been addressed by concentrating only on SNPs represented on both arrays, by strict quality control, and by analysis of only large, rare CNVs, which, in accordance with previous findings (17, 21), can be reliably called.
