If there is a sample mix-up, the measurements will not correspond to the correct samples.
Based on our classificatory approach (see Methods), a total of nine recombinants with score at least 6.0 could be identified (Table 2), two of which can be regarded as partners in a sample mix-up.
We will show below, however, that in both simulations and real tumor samples, MixHMM can reliably detect the CNV states up to seven copies in a sample mixed with up to 0.6 proportion of normal cells.
A sample mixed with a smaller percentage of DNA from a different genotype (strain) may increase the hybridization background signal.
A total of 2 μl of each DNA sample (50 ng) was used in a 5 μl sample mix to genotype 47 SNP assays and one non-reagent control.
For SNP genotyping on the dynamic array chips, a 5 μl sample mix was prepared for each sample containing 1× TaqMan® Universal Master Mix (Applied Biosystems, Foster City, CA), 1 × GT Sample Loading Reagent (Fluidigm PN 85000741), 0.05 units/μl additional Taq-Gold polymerase (Applied Biosystems) and either 50~60 ng of genomic DNA, or diluted pre-amplified DNA.
As demonstrated in this study, the use of IDM to derive Ce or E involves only a few simple steps, i.e., addition of isotope-labeled analogues to a sediment sample, mixing the sample for a relatively short duration (e.g., 24 h), and analyzing the aqueous concentrations of both labeled and nonlabeled (native) HOCs using a MS-equipped chromatographic system.
A second solution (the sample mix) is flowed through the segment so that the first (assay) solution is displaced into the reaction chamber, and a volume of the second (sample) solution enters the chamber.
Digestion of an unknown sample mixed with SILIS generates a labeled and a nonlabeled version of each peptide.
