To test their polymorphisms in other rice varieties, we further analyzed them by genomic DNA PCR amplification in a panel of 20 rice cultivars, including Nipponbare and 9311, using the same set of InDel markers plus 100 pairs of SSR primers for comparison (Additional file 7: Table S7; Fig. 4).
Blocking primers, in comparison, have been shown extremely effective at excluding predator DNA in some situations [23].
Genome-wide computational analyses of functional elements such as the promoters should enable the selection of subsets of FR primers for comparison between disease and normal cohorts.
After coarse morphological identification (cirri I/II, mandible), individual specimens were 'barcoded' using universal [42] mitochondrial cytochrome oxidase I (mtCOI) primers for comparison with previous taxonomic and phylogenetic analyses of this genus (e.g., [7], [21], [22], [43]).
Crossing point data were first adjusted to reflect the efficiency of primer pairs by comparison to standard curves, (based on dilution series over a total dynamic range of 1∶1,000 or 1∶10,000 for positive control cDNAs).
We found that purification of final libraries with AMPure XP beads efficiently removed primer dimers in comparison to column based PCR purification (data not shown).
Given the quality of our primers and our comparison of different tissue types, we did not think that we would be able to accurately estimate copy number in partial heterozygotes from allele peak size as described in Esselink et al. (2004).
A combined score for each primer pair allows their comparison and ranking within and between candidate regions.
Comparison of primer sequences of the two SSR markers against the peach draft genome revealed that the Gr interval is about 7.9 Mb in physical size, ranging from 11.9 Mb to 19.8 Mb on LG6.
In silico comparison of primers and probes, and analytical assessment with a range of near-neighbor Mycoplasma species and multiple bacterial respiratory pathogens demonstrated 100% analytical specificity of the assay.
