  • Publication number: 20130023447
    Abstract: The invention relates to a procedure for linking cognate pairs of VH and VL encoding sequences from a population of cells enriched in particular surface antigen markers. The linking procedure involves a multiplex molecular amplification procedure capable of linking nucleotide sequences of interest in connection with the amplification, in particular polymerase chain reaction (multiplex PCR). The method is particularly advantageous for the generation of cognate pair libraries as well as combinatorial libraries of variable region encoding sequences from immunoglobulins. The invention also relates to methods for generation of chimeric human/non-human antibodies and expression libraries generated by such methods.

  • Publication number: 20120009623
    Abstract: The invention relates to a method for manufacturing recombinant anti-RSV antibodies and antibody compositions. The method comprises obtaining a collection of cells transfected with a collection of variant nucleic acid sequences, wherein each cell in the collection is transfected with and capable of expressing one distinct anti-RSV antibody. The cells are cultured under suitable conditions for expression of the anti-RSV antibody/antibodies. The nucleic acid sequence is introduced into the cells by transfection with expression vectors, which avoid site-specific integration. The present method is suitable for manufacturing recombinant mono- and polyclonal anti-RSV antibodies for therapeutic uses.

  • Patent number: 7887805
    Abstract: The invention relates to the field of recombinant antibodies for use in human cancer therapy. More specifically the invention provides compositions or mixtures of antibodies capable of binding human EGFR. Antibody compositions with 3 or more antibodies showed synergy in reduction of proliferation of representative cancer cell lines. Advantageous results have also been obtained with a composition comprising two different chimeric anti-hEGFR antibodies which show a new mechanism of action based on rapid and efficient receptor internalisation, induction of terminal differentiation and subsequent tumour eradication in an animal model. The antibodies of the invention can be manufactured in one bioreactor as a polyclonal antibody.

  • Publication number: 20100310558
    Abstract: Multiplex overlap-extension RT-PCR provides an efficient method of linking two or more nucleotide sequences encoding for domains or subunits of a heteromeric protein, in a single reaction. Especially, the linkage of variable region encoding sequences from e.g. immunoglobulins, T cell receptors or B cell receptors is eased with the method of the present invention. This allows for a more efficient way of generating libraries of variable region encoding sequences. The capability to perform the multiplex overlap-extension RT-PCR using template derived from an isolated single cell enables the generation of cognate pair libraries in a high-throughput format.

  • Publication number: 20020012950
    Abstract: A monoclonal antibody which binds a human endothelial type plasminogen activator inhibitor (PAI-1) produced by dexamethasone-treated human HT-1080 fibrosarcoma cells may be used, inter alia, for determining PAI-1 protein abundance in tumor tissue or a sample of a body fluid. Measurements of this parameter may be useful in predicting the presence or metastasis of a tumor, or of predicting the progression of a known malignant tumor.

  • Patent number: 5422245
    Abstract: In a method of producing monoclonal antibodies against endothelial type plasminogen activator inhibitor and immunologically similar inhibitors myeloma cells are fused with antibody-producing cells obtained from mammals which have been immunized with said plasminogen activator inhibitor or with antibody-producing cells, which in vitro have been immunized with said plasminogen activator inhibitor and the hybridomas producing antibodies against the above mentioned inhibitor are selected. The antibody-producing cells are preferably spleen cells or lymph node cells, most preferably spleen cells, obtained from mice immunized with the above mentioned inhibitor.
