“…The spectrum obtained for b-Lg A (Fig. 3A) shows a typical mass spectrum profile with a major peak at 18,367.4 Da, corresponding to the molecular mass of the protein (Imre, Zsila, & Szabo, 2003;Leonil et al, 1997;Zsila, Imre, Szabo, Bikadi, & Simonyi, 2002). Other minor peaks observed at 18,582 and 18,694 Da are likely due to lactosylated conjugates (Leonil et al, 1997;Zsila et al, 2002).…”
