METHODS, COMPOSITIONS AND KITS FOR CONCENTRATING TARGET ANALYTES FROM A BULK FLUID SAMPLE
Document Type and Number:
WIPO Patent Application WO/2024/093522
Kind Code:
A1
Abstract:
The present disclosure relates to methods, compositions, and kits for concentrating and purifying one or more target analyte (s) from a bulk fluid sample. In some embodiments, the methods involve at least two first aqueous two-phase system (ATPS) compositions. Some embodiments provide a kit comprising at least two ATPS compositions, and a binding buffer. Other embodiments provide methods of treating bladder cancer in a patient in need thereof.
