Abstract: A percutaneous targeting device comprises a body holding an extension. The body has a target guide holding a target pin which may be a K-wire. The extension has two guide sleeves, holding a guide wire. All wires are held in a common plane. The guide wires serve as a guide for cannulated fixation screws. The extension is movable against the body to adjust the angle between the target pin and the guide wires.

Abstract: The present invention relates to novel complexes of major histocompability complex (MHC) molecules and uses of such complexes. In one aspect, the invention relates to single chain MHC class II complexes that include a class II ?2 chain modification, e.g., deletion of essentially the entire class II ?2 chain. In another aspect, the invention features single chain MHC class II which comprise an immunoglobin constant chain or fragment. Further provided are polyspecific MHC complexes comprising at least one single chain MHC class II molecule. MHC complexes of the invention are useful for a variety of applications including: 1) in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, and 2) methods for suppressing or inducing an immune response in a mammal.

Abstract: Disclosed are methods for identifying compounds that modulate an immune complex that includes a T cell receptor (TCR) and a major histocompatibility complex (MHC) antigen. The invention has many useful applications including providing high throughput screening assays for detecting compositions that can modulate an immune response.
