    • 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.
    • 本文描述了用于从生物样品中分离和加工微粒的方法,装置和组合物,以及获得和使用微粒用于生物标志物发现的方法。 生物样品包括无细胞流体,例如血浆,血清,脑脊髓液,尿液和唾液以及条件培养基。 条件培养基是用于在体外繁殖细胞的液体生长培养基。 从无细胞流体中纯化微粒是有挑战性的,通常通过长时间超速离心来实现。 本文描述的是用于从无细胞流体和条件培养基有效收获和加工微粒的替代方法。 本文所述的实施方案涉及从源自人和动物细胞繁殖的条件培养基中回收的微粒及其内容物作为疾病和病理状态的诊断和预后的生物标志物的来源。
