Modelling homopolymer uncertainty during clustering allows Séance to produce fewer low abundance OTUs with duplicate labels.
During the initial stages of SCX, buffer blanks were run after each sample, and the resulting fractions were assessed for peptide carryover; apart from peptides corresponding to a few high abundance proteins, we found very few peptides (data not shown).
It is significant that there were a few higher abundance peaks in the spectrum shown in Figure 3b, such as m/ z 818.58, 846.62, 708.45, and 736.48.
While the authors were unable to conclude whether this high redox buffering capacity of protein thiols is the work of a few high abundance, highly cysteine-enriched proteins or a contribution of the majority of thiol-containing proteins, our data suggest that the majority of yeast protein thiols have the capacity to undergo reversible redox modifications and thereby serve as redox buffer.
Overall, the data suggest that degradation is limited to a few low-abundance proteins.
With the exception of Ad and Mj, there were three or fewer methylation-transcript abundance associations, and in all instances they were unique to one person.
Compared with protein coding RNA, lncRNAs are typically shorter with fewer exons, less abundance, less coding potential and more restrictions to particular tissues or cells [ 13].
The organic apple and Gorgonzola salad sounded promising, but the apple slices were few amid an abundance of mesclun.
And because there is so much income churning in the land of abundance, few families stay at the bottom or the top for very long.
After extensive purification of the enzyme by a series of five different chromatographic steps, a few small low abundance RNAs copurified with the activity.
