  • Publication number: 20050176079
    Abstract: A method for detecting the presence or amount of an analyte in a sample is described. The method involves contacting the surface of the solid support with the sample and detecting analyte on the surface of the solid support. A bioconjugate comprising a polypeptide conjugated to a polysaccharide is deposited on the surface of the solid support and the polypeptide of the bioconjugate can interact with the analyte. The analyte can be an antibody and the polypeptide can comprise an antigenic determinant of the antibody. By conjugating the polypeptide to the polysaccharide, the antibody can be detected at lower levels than if the non-conjugated polypeptide were employed. Exemplary solid supports include membranes and assay plates (e.g., ELISA plates). The polysaccharide is preferably a hyaluronic acid or a hyaluronic acid analogue. The method can be used to diagnose diseases such as SARS. Methods of making polypeptide-polysaccharide bioconjugates are also provided.

  • Publication number: 20050014613
    Abstract: A lateral motion exercising apparatus provides a pair of vertically oriented axles engaged with a frame. A pair of support struts are rotationally engaged with the axles. A rigid link is pivotally joined at its terminal ends with the support struts in a manner for maintaining the support struts in parallel alignment as they rotate about the axles. A pair of platform struts is engaged pivotally at proximal ends of the support struts, the pivots enabling each of the platform struts to rotate vertically about its distal end. The proximal ends of the platform struts are constrained to move in opposing vertical motions in coordination with rotations of the support struts to produce a skating-like motion to a user standing on the platform struts.
