IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
EnglishThe murine monoclonal antibody (MAb) MOv2 was found to be directed against the carbohydrate moieties of different kinds of molecules expressed on a human ovarian cystoadenocarcinoma. To define further the glycoconjugates carrying the MOv2-defined epitope, different procedures were used to analyze materials from surgical specimens and carcinoma cell lines. SDS-PAGE and immunoblotting showed glycoprotein molecules migrating in the gel as high and intermediate molecular weight components. A low-molecular-weight band, migrating approximately with the dye front, was also immunostained by MOv2. On the other hand, the immunostaining of high-performance thinlayer chromatography (HPTLC) of the total glycolipid extract and its neutral and acid fractions, after DEAE chromatography, showed selective reactivity with a neutral glycolipid. Reanalysis by immunoblotting of this glycolipid band scraped off the HPTLC plate indicated that it corresponds to the low-molecular-weight component. Periodate oxidation and Pronase digestion further demonstrate the saccharide nature of the determinant on both types of glycoconjugates. In conclusion, we report evidence that with a single analytical procedure, i.e., immunoblotting, it is possible to recognize the same carbohydrate determinant carried on both protein and lipid molecules.
