Loamy soils (these include silts in this classification system), which are generally of a high quality, start at much higher nFK values than clays (100 mm vs. <50 mm).
However, all these methods require high quality starting material, and DNA from many types of samples such as chromatin immunoprecipitation (ChIP) products, formalin-fixed paraffin-embedded (FFPE) tissues, or ancient remains is highly fragmented.
While sequencing of the entire transcript provides abundant biological information, a significant limitation of this technique is it requires high quality starting RNA.
In contrast, the aim of 3SEQ is to perform genome-wide expression quantification, which can be performed on both high quality starting RNA as well as degraded RNA.
Since these techniques attempt to sequence the entire RNA transcript, the successful application of these methods for expression profiling depends on the presence of high quality starting total RNA.
High quality starting RNA is essential for the cDNA-AFLP technique.
In order to find the best reference genes for relative quantification, a high quality starting material is needed.
197,888 ESTs (57.4% of the EST sequences) had information about high quality start or end of sequencing reads.
cDNA libraries constructed according to the method presented also yield high full-length percentages for large cDNAs/ORFs when high quality starting mRNA is used.
So what about high-quality starts — say, starts lasting at least seven innings, with no more than three earned runs? Win or lose, almost every such start is an ace-worthy performance.
He gives what we could call a high-quality start (seven innings, no more than three earned runs) nearly as often -- 20 of 28.
