New yersinia study findings reported from University of Washington
December 2nd, 2008
"Lipid A isolated from several bacteria (Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, and various strains of Yersinia) showed abundant formation of pyrophosphate anions upon ion dissociation," scientists in the United States report. "Pyrophosphate [H3P2O7](-) and/or [HP2O6](-) anions were observed as dominant fragments from diphosphorylated lipid A anions regardless of the ionization mode (matrix-assisted laser desorption ionization or electrospray ionization), excitation mode (collisional activation or infrared photoexcitation), or mass analyzer (time-of-flight/time-of-flight, tandem quadrupole, Fourier transform-ion cyclotron resonance mass...
