Abstract: Herein is reported an enzyme linked immunosorbent assay for the detection of anti-drug antibodies against a drug antibody in a sample comprising a capture drug antibody and a tracer drug antibody, wherein the capture drug antibody and the tracer drug antibody are employed in a concentration of 0.5 ?g/ml or more, the sample is incubated simultaneously with the capture drug antibody and the tracer drug antibody for 1 to 24 hours, the capture drug antibody and the tracer drug antibody are derivatized via a single lysine residue, the sample comprises 10% serum, and oligomeric human IgG is added to the sample prior to the incubation with the capture drug antibody and the tracer drug antibody.
Abstract: 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 ?-A4 peptide/A?4. 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.

Abstract: The present invention relates to the use of regulatory sequences for mediating specific, early transient expression in proliverative neuronal determined cells. Furthermore, the uses of recombinant nucleic acid molecules comprising said defined regulatory sequences for mediating specific, early transient expression in proliverative neuronal determined cells as well as for the generation of non-human transgenic organisms and/or host cells are disclosed. In addition, the invention provides for transgenic non-human animals and/or host cells comprising said regulatory sequences and/or recombinant nucleic acid molecules. The invention also describes methods for the preparation of such vectors, host cells and transgenic non-human animals as well as methods for the detection and/or isolation of neuronal determined cells.
