The aim of this work was to develop a method of target antigen quantitative evaluation in a complex protein mixture by MALDI mass spectrometry using isotopomers, peptides that contain stable isotopes of oxygen. Cell lysates of A549 cells infected with influenza virus A were used as a complex protein mixture. The object of study was the NS1 protein. This protein is synthesized in the infected cells during the viral life cycle. The proposed procedure of quantitative evaluation was tested on purified protein NS1 and then applied to the lysed cells that had been previously separated by SDS-PAGE.
