Abstrakt: S-Aminoethylated-alpha A and -beta A globin tryptic peptides separated by reversed-phase high-performance liquid chromatography have been analysed by plasma desorption mass spectrometry. Almost all the expected alpha A and beta A tryptic fragments were tentatively assigned relative to the known globin chain sequences based on the molecular weight obtained by plasma desorption mass spectrometric analysis of the purified peptides. The application of plasma desorption mass spectrometry for structure elucidation of a haemoglobin alpha-chain variant revealed the first case of Hb Hasharon in Hungary.
