Abstract: A method for enabling a user to select and interact with text, lines, or paragraphs of a document, in the case where the document is available as a PDF or image. Embodiments enable the representation of a document to go beyond simple extraction of text, including organizing the text into logical groups of benefit to a user, such as paragraph, header, footer, or table (as examples), and labelling them as such. This facilitates subsequent processing, including application of machine learning (ML) algorithms to leverage this explicit information.

Abstract: The present invention provides recombinant peptides that specifically and selectively bind to the human milk fat globule (HMFG) antigen, BA46. In particular, the present invention provides recombinant variants of the Mc3 antibody, including humanized versions of Mc3. The variant Mc3 peptides are particularly useful for diagnostic, prognostic, and therapeutic applications in the field of breast cancer. The present invention also provides methods for the humanization of antibodies such as murine monoclonal antibodies. The novel humanization methods are applied to the production of humanized Mc3 antibodies and it is shown that these humanized antibodies retain the ability to engage in high affinity binding to their cognate antigen. Such humanization enables the use of these antibodies for immunodiagnostic and immunotherapeutic applications in humans.

Abstract: An in vitro solid-phase, competitive assay for detecting the presence of a peptide analyte in a biological sample comprises contacting a fusion protein, of first and second peptides, with a solid supported first antibody or fragment thereof, which binds the first peptide, adding a biological sample containing the peptide analyte and a second antibody or fragment thereof which binds the peptide analyte and the second peptide. The second antibody is allowed to bind any free analyte present in the sample, and to form solid supported complexes of fusion protein and antibody. The amount of solid supported second antibody detected is then compared to a control. When the amount of peptide analyte in the sample increases the amount of second antibody bound to the solid support decreases. An optional final addition of an antibody-binding molecule helps detect the solid supported complexes of the fusion protein and the second antibody or fragment.
