The instrument can achieve an excellent charge discrimination, thus allowing to assess the elemental composition of charged cosmic rays at relativistic energies.
MSEP similarity between any two protein molecules is a measure of the similarity in their composition of charged residues.
The group H proteomes also had the lowest composition of charged amino acids among the 11 groups.
The data used was very large, consisting of 27,000 targets from over 120 organisms and a number of important features were inferred that correlated with success including percentage composition of charged residues, occurrence of hydrophobic patches and length.
Sequences of temperate and subtropical octopods overlapped and occurred between those of polar and tropical octopods in the PCA plots with respect to their composition of charged amino acids (Fig. 6).
To test this substrate and the collection concepts, we used a commercially available electrospray system (TSI Inc., Model 3480), which is capable of preparing various aerosols containing a known composition of charged and neutral analyte molecules.
For instance, using the data from the TargetDB, Goh et al. (2004) found that conservation of the sequence across organisms, composition of charged residues, occurrence of hydrophobic patches in the sequence, number of binding partners and chain length influence the feasibility for the high-throughput structure determination.
These polymers all have different compositions of charge centers ranging from primary, secondary, and tertiary amines.
Biosorbent and sorbate characteristics include composition, structure, type of charged and uncharged functional groups, and particle size.
To determine the role of solution composition on charging in these experiments, nanoESI mass spectra of polypropylenimine hexadecaamine dendrimer, generation 3.0 (DAB-16), were obtained under similar conditions.
