  • Patent number: 6592826
    Abstract: In a vacuum chamber, which has at least two vacuum regions, substances, especially fluids, are transported in a directed manner from one region into the other region by the application of a suitable vacuum. As a result, it is possibly by the use of filter supports or receiver supports to transport a fluid automatically through corresponding filter supports during a plasmid preparation. The vacuum chamber is charged by means of a gripping robot that operates automatically and is switched by a suitable valve control means. By incorporating the vacuum chamber with its gripping robot and the control means into a pipetting robot system, automatic plasmid preparation, for example in accordance with the Qiagen protocol, is possible.

  • Patent number: 6518067
    Abstract: The disclosed synthesis system is based on the idea of designing a synthesis and treatment procedure, substrates and anchor groups which enable biomolecules to be simultaneously produced in an entirely automatic manner. By using a pipetting robot to dispense the reagents, the reaction column can be arranged in a format suitable for subsequent treatment. For a pipetting robot to carry out even water-sensitive or air-sensitive synthesis protocols, certain structural measures must be taken. The operation principle of the automated and the synthesis sequence are described below as an example of a possible solution. The automation can work with conventional substrates and reagents. Handling, however, is simplified by new, specially adapted substrates and anchor groups. A special, simultaneous purification and aliquot portioning process improves product quality and makes the device easier to use.

  • Patent number: 6475756
    Abstract: Murine retroviruses are the most important transfer systems for human gene therapy. However, their application is currently limited. One of the major restrictions both for an application in vivo resides in the problem that this virus type is sensitive to inactivation by human complement factors. Our invention overcomes this limitation. We have modified murine recombinant retroviruses in a way that they are resistant to human complement factors. This was achieved by genetic modification of the retroviral surface protein env which is responsible for receptor interaction: the receptor interacting domain of env was fused to catalytically active domains of human complement inactivation factors. These modified env were expressed in complement-sensitive cells and specifically integrated into virus particles. By this strategy cells and viruses are generated that are fully resistant to complement attack.

  • Publication number: 20020106376
    Abstract: A common problem in human vaccinology is the limited availability of efficient and non-toxic adjuvants capable of promoting mucosal responses. The potential usefulness of fibronectin-binding protein (SfbI) of Streptococcus pyogenes as immunological adjuvant was assessed using ovalbumin (OVA) as a model antigen. Mice were immunized by intranasal route either with soluble OVA or OVA covalently coupled to SfbI. Immunization with OVA-SfbI resulted in the elicitation of about 100-fold higher titres of anti-OVA serum IgG than using OVA alone. The anti-OVA IgG subclass pattern was dominated in both groups of mice by IgG1, followed by IgG2b, IgG2a, and IgG3. Immunization with OVA-SfbI also resulted in the elicitation of OVA-specific IgA in lung washes (24% of the total IgA), which was absent in mice immunized with OVA alone. Spleen cells from OVA-SfbI immunized mice also gave a much stronger proliferative response to in vitro restimulation with soluble OVA.
