In the previous analysis we have compared "absolute" levels of histone modifications at multiple classes of loci to discover patterns of co-occurring marks that discriminate among them.
We have compared the enrichment of histone modifications on the pluripotency genes Sox2 and Oct4 to those on β-globin, a gene that shows no transcriptional activation in injected oocytes [ 12].
Studies examining DIS and SA have compared these strategies to conventional care or modifications of the initial strategy [ 8].
Then we have compared laser patterned GDLs with chemically treated samples to evaluate the differences between these two methods of the PTFE content modification.
Fluorescent probes have been used to evaluate different steps of the freezing process [ 10], and compare modifications in freezing [ 47] or thawing techniques [ 11].
Chemical modification of a neat polymer followed by membrane formation and modification of just formed membranes have been compared to plasma action.
Two of the modifications made to the Weaver Dunn technique have been compared (CC fixation with PDS vs hook plate) [17].
In this analysis, we have systematically compared the CID and ETD fragmentation patterns for the large majority of the peptides that do not contain such labile modifications.
About 21 percent of eligible Bank of America borrowers have received program modifications, compared with 44 percent at Citigroup, 37 percent at Wells Fargo and 32 percent at JPMorgan Chase.
The performance of the proposed modifications has been compared with other five recently developed state-of-the-art techniques.
