    摘要: The present invention relates to a purified antibody molecule preparation being characterized in that at least one antigen binding site comprises a glycosylated asparagine (Asn) in the variable region of the heavy chain (VH). More specifically, a pharmaceutical and a diagnostic composition comprising said antibody molecule and antibody mixtures are provided which is/are capable of specifically recognizing the β-A4 peptide/Aβ4. The present invention relates in particular to a mixture of antibodies comprising one or two glycosylated antigen binding sites with a glycosylated asparagine (Asn) in the variable region of the heavy chain, i.e. mixtures of isoforms of antibodies which comprise a glycosylated Asn in the variable region of the heavy chain (VH). Also disclosed are compositions or antibody preparations comprising the specifically glycosylated antibody isoforms. Furthermore, the pharmaceutical and diagnostic uses for these antibodies are provided. The antibody isoforms may for example be used in the pharmaceutical intervention of amyloidogenesis or amyloid-plaque formation and/or in the diagnosis of the same.

    摘要: The current invention is directed to a method for determining amino acid sequence mutations in a produced polypeptide, comprising the following steps of a) providing a sample of a produced polypeptide, b) incubating the polypeptide in the sample with a protease, c) performing a two dimensional analysis using reversed phase chromatography coupled with a high resolution mass spectroscopy (FT-ICR/FT-orbitrap) and MS/MS analysis of the amino acid sequence fragments of the peptides, d) data evaluation by comparing the LC-MS data sets obtained for the samples side by side with the data set of a reference sample, by searching for differences in the signal intensities at given retention times and by evaluation of differential signals with respect to amino acid sequence mutations. The reference sample for data evaluation (d) can be either a well characterized standard or one of the samples to be analyzed.
