This behavior would be expected if the water beam predominantly enhances the yield of the [M + H]+ ion and most fragment formation results from fragmentation of this ion.
Already fragmented ions were excluded from fragmentation for 45 s.
In the model building stage, initial molecular structures are constructed by assembling fragment templates, which are generated from fragmentation of the input molecular graph along sigma bonds.
The orientation run was performed on transcripts previously purified by the MirVana isolation kit (Ambion) and prepared using a dir-mRNA-SEQ protocol starting either from fragmentation with zinc or from non-fragmented transcripts.
Furthermore, the fragmental ion at m/ z 241 from fragmentation pathway A was present in the EPI spectrum, and the ion at m/ z 327 was 86 Da larger than the ion at m/ z 241.
The overhangs resulting from fragmentation were converted into blunt ends using T4 DNA polymerase, the Klenow fragment, and T4 polynucleotide kinase.
Trees across the world are stressed already from fragmentation, air pollution, and other problems, he said.
Here we have moved away from fragmentation as "imaginal adventure"; now it is a labyrinth, constructed to confound us.
In financial markets, regulatory enthusiasm has been tempered by a fear: that markets will suffer from fragmentation.
In bacteria and archaea, methylation forms an essential part of the immune system by protecting DNA molecules from fragmentation by restriction endonucleases.
He said a British post-mortem showed that she had died from "fragmentation" injuries to her head and chest caused by the grenade.
