  A novel mass spectrometry (MS)-based approach to the identification of host-derived biomarkers (BMs) in the circulating low-molecular-mass (LMM) fraction ( <25 kDa) of blood proteome was tested in a murine model . DBA2/J mice were challenged intraperitonially with spores of either the toxigenic B. anthracis Sterne strain (pXO1 + , pXO2 - ) that is virulent in DBA/2 mice or the nontoxigenic, non-virulent delta Sterne strain (pXO 1 - , pXO2 - ). Serum samples were obtained at multiple time points and seperated by continuous flow denaturing gel electrophoresis followed by Coomassie staining to i so- late the LMM archive for subsequent MS identificati on. Peptide fragments derived from more than 200 protei ns displayed low-variance differential abundances betw een lethal and non-lethal challenges. Several proteins from the.. View More»
