  • Patent number: 11701657
    Abstract: A column-based device and method for retrieving cells of interest were enclosed. The said device comprises a column comprising (i) an inner wall defining an inner chamber with inlet and outlet openings, (ii) a perforated plug disposed adjacent to the outlet opening, (iii) a sleeve insert with a channel and disposed within the chamber and adjacent to the perforated plug, and (iv) a filtering means housed within sleeve insert sandwiched between two sealing means. In particular, Tumor-derived endothelial cell clusters (TECCs) as characterized multiple nuclei, expression of endothelial markers (PECAM1, VWF and CDH5), and non-expression of leukocyte, megakaryocyte and platelets markers, may be retrieved using the disclosed device. Also encompassed are methods, reagents and kits for the diagnosis and prognosis of cancers by detecting for the presence of TECCs isolated from blood samples using the claimed device.

  • Patent number: 11186865
    Abstract: A method of simultaneously analyzing RNA and DNA in a sample, the method comprising the step (a) contacting the sample with a reverse primer from a first primer pair directed to a target RNA region to effect reverse transcription of RNA into cDNA with a reverse transcriptase; (b) subsequently contacting the sample with (i) a forward primer from the first primer pair directed to a second cDNA region, (ii) a forward and a reverse primers from a second primer pair targeted to a DNA region, and (ii) a DNA polymerase to simultaneously amplify the target cDNA and target DNA region; and (c) analyzing the amplified target cDNA region and/or amplified target DNA region. Also encompassed are uses of the method to analyze gene expression and mutations, kits comprising primers, enzymes, buffers.

  • Patent number: 10151755
    Abstract: The invention relates to biomarker assays based on protein/peptide biomarkers which show a pronounced differential behaviour between healthy and cancerous sample proteomes e.g. by mass spectrometric measurement and/or antibody-based assays such as an Enzyme-Linked Immunosorbent Assay (ELISA) determination of the protein biomarkers in serum, plasma or blood itself.
