chromatography using monoclonal antibody (mAb) BT-2, which binds all -versions independent of their posttranslational modifications, and analyzed its N-glycosylation state after two-dimensional gel electrophoresis (2-DE) using sensitive immunoand lectin-blot analyses. Blots from crude resulted mostly in Nand O-glycosylated neurofilaments that incidentally comigrated with in SDS-PAGE, but were separated by the pH-gradient in 2-DE. Thus N-glycosylated versions present in the affinity purified were enriched by a lectin-based affinity chromatography. The eluate was separated by 2-DE and probed with an antimAb and lectins. Taken together, appears to be Oand N-glycosylated at a low level. This raises the question, if the glycosylation levels detected in PHFare really diseasespecific or if it is only related to different aggregation characteristics unand N-glycosylated species.
