  • Dispersive pipette extraction system for purification of large biomolecules
    Patent number: 11161107
    Abstract: The present invention provides a disposable pipette tip for dispersive solid phase extraction (SPE) that allows for rapid, automatable purification of large biomolecules, such as nucleic acids, proteins and polypeptides without the need for additional tools such as centrifuges, magnetic plates or vacuum manifolds. The pipette tip is designed for optimal biomolecule isolation while maintaining sample integrity. Optimized methods of using the dispersive pipette extraction system for isolation of large biomolecules are also provided.

  • BIOMARKER FOR DIAGNOSIS OF NEUROMYELITIS OPTICA OR MULTIPLE SCLEROSIS AND USE THEREOF
    Publication number: 20180231571
    Abstract: Disclosed herein is a use of glial fibrillary acidic protein (GFAP) and fibronectin as markers for distinguishing between neuromyelitis optica (NMO) and multiple sclerosis (MS). The biomarker composition of the present disclosure for distinguishing between NMO and MS enables early diagnosis of NMO or MS which are difficult to be differentiated from each other at an early stage and appropriate treatment to be applied, and can be utilized in the study of NMO and MS through proteome analysis of cerebrospinal fluid exosomes in patients.
