when western blots of proteins of infected cells which had been lysed in sds were probed with anti-lassa virus serum or stained for glycoproteins , four virus-specific bands were apparent : the n , g1 and g2 proteins seen in purified virus , and a glycoprotein of molecular weight 72000 which probably corresponds to the envelope protein precursor ( gpc ) seen in other arenavirus systems .
