Abstract: The present invention relates generally to the field of antibody detection, and in particular relates to methods involving the detection of autoantibodies relating to lung cancer in a sample comprising patient bodily fluid. In particular, the present invention relates to a method of detecting lung cancer in a mammalian subject by detecting three or more autoantibodies in a test sample, wherein three of the autoantibodies are immunologically specific for the tumour marker antigens p53, SSX1, and either p62 or KOC. The invention also relates to in vitro methods of determining an autoantibody profile, methods of diagnosing and treating lung cancer, methods of predicting response to a lung cancer treatment, use of a panel of three or more tumour marker antigens for the detection of lung cancer, and kits for the detection of autoantibodies.

Abstract: The present invention relates to a method of detecting liver cancer in a mammalian subject by detecting an antibody in a test sample comprising a bodily fluid from the mammalian subject, wherein the antibody is an autoantibody immunologically specific for a tumour marker protein selected from the group consisting of MMP9, AIF1, EpCAM and CDKN1B, which method comprises contacting the test sample with a tumour marker antigen selected from the group consisting of MMP9, AIF1, EpCAM and CDKN1B and determining the presence or absence of complexes of the tumour marker antigen bound to autoantibodies present in the test sample where the presence of said complexes is indicative of the presence of liver cancer.

Abstract: The present invention generally relates to the field of antibody detection, and in particular relates to assays for the detection of antibodies in a sample comprising patient bodily fluid. The invention provides a method of detecting an antibody in a test sample comprising a bodily fluid from a mammalian subject, wherein the test sample is contacted with a plurality of different amounts of an antigen specific for the antibody, the amount of specific binding between the antibody and the antigen is detected and the presence or absence of antibody is determined based upon the amount of specific binding between the antibody and the antigen and a secondary curve parameter arising from a curve of the amount of specific binding versus the amount of antigen for each amount of antigen used.

Abstract: The disclosure provides a bioreactor that allows steady-state oxygen gradients to be imposed upon in vitro culture systems. The bioreactor system of the disclosure has been applied to liver zonation and have shown that physiological oxygen gradients contribute to heterogeneity of tissue cultures in vitro.
