    摘要: Described herein are methods, devices, and compositions for fractionation and processing of microparticles from biological samples, and to methods for obtaining and using the microparticles for biomarker discovery. Biological samples include cell-free fluids, for example blood plasma, blood serum, cerebrospinal fluid, urine, and saliva, as well as conditioned media. Conditioned media is the liquid growth media used to propagate cells in vitro. Purification of microparticles from cell-free fluids is challenging, typically accomplished by prolonged ultracentrifugation. Described herein is an alternative method for efficiently harvesting and processing microparticles from cell-free fluids and from conditioned media. Embodiments described herein relate to use of the microparticles and their contents recovered from conditioned media derived from propagation of human and animal cells, as a source of biomarkers for diagnosis and prognosis of diseases and pathological conditions.

    摘要: The present invention concerns the methods and compositions for preparing a tissue section or biological sample, particularly to preserve RNA in the section or sample, by not exposing or contacting the sample or section to a solution that is composed of mostly water. Tissue sections can be fixed, stained, and dehydrated for subsequent manipulation, including laser capture microdissection (LCM) for further analysis using methods and/or compositions of the invention.

    摘要: The current invention relates generally to methods for rapid fractionation of WBCs from whole blood using a proprietary leukocyte depletion filter, which concentrates and partially purifies the WBCs, and for stabilizing the RNA patterns in the fractionated cells. The invention further relates to methods of extracting the RNA from the fractionated cells and using such nucleic acids in any of a variety of molecular biology procedures including, for example, expression profiling.

    摘要: Provided is a sensitive method to specifically detect nucleic acid sequences using a combination of DNA replication based signal amplification (e.g., PCR) and lateral flow analyte detection. The disclosed method uses a dual-labeled DNA probe complementary to a region of the target DNA sequence. Cleavage of the probe, caused by the presence of the amplified DNA target, is detected using lateral flow methods.
