The isoelectric point and molecular mass of theSBEs were calculated using ExPASy, and the data are presented in TableS3. The conserved domains and SBE proteins were predicted and annotated by using the NCBI database and MEME software. The polypeptides were deduced and analyzed by PeptideMass and ...
This was attributed to the viscosity induced slow mass transfer. At 1 M HNO3, the D values for uranyl and thorium follow the trend C4mimNTf2 > C6mimNTf2 > C8mimNTf2, which was ascribed to the enhancement in organophilicity of the cation on increasing the length of the side chain and ...

Electrospray ionization mass spectrometry (ESI–MS) is a very efficient technique for the characterization of metallosurfactants, as the metal often contributes a characteristic isotope pattern. Figure 2a,b shows two representative ESI–MS patterns for Ce-DO3A-C4-SO3 and Sc-DO3A-C4-SO3. For ...
The method is a quite simple and convenient and feasible method for preparing the zeolite molecular sieve of various (especially high-silica) microcellular structures, and is more applicable to mass industrialized production. The method of the inventionprovides a good application way for the ...

In this modified method, Aβ fibrils are excluded from the Sepha- dex G-75 column since they have molecular mass in excess of 100 kDa, which is the exclusion limit of the col- umn. Therefore, Aβ fibrils are not present in our SEC monomeric or SEC oligomeric samples as previously ...
Matrix-assisted laser desorption ionization time-of-flight mass spectrometric analysis confirmed the identity of the polypeptide and indicated that the protein contained 16 internal seleno-l-methionine residues, whereas the N-terminal modified methionine residue had been processed in E. coli. Enzyme ...
The precursor mass tolerances were set to 20 and 4.5 ppm for the first and main search, respectively. The fragment mass tolerance for the HCD MS/MS spectra was set to 20 ppm. The enzyme specificity was set to complete tryptic digestion. Peptides with a minimum length of 6 amino acids ...
(13C NMR), as well as that of the mass spectral data, were used as the appropriate characterization techniques for the chemical structures of all newly synthesized compounds. The newly prepared compounds were examined as an anti-inflammatory, antibacterial agents (againstE. coli(Escherichia coli) ...
