Publication number: 20250034546Abstract: The instant invention provides a deblocking double-layer chromatography and cassette for isolating nucleic acids from liquid biopsy samples such as urine with large sample volumes, small nucleic acid sizes, and low nucleic acid concentrations. Compared with the prior art of Ding et al. (U.S. Pat. No. 9,163,230) which proved the principle of double-layer chromatography comprising a positively charged DEAE membrane and a silica membrane, we further explored and optimized the membrane compositions and solution compositions for plasma and urine samples. More importantly, we set up a “deblocking” mechanism to overcome a “blocking” problem that the membrane is blocked by solid particles in the plasma and urine samples, thus greatly increasing its flowability. In addition, it omits a pre-filtering step, thus particularly suitable for its automation.Type: ApplicationFiled: July 12, 2024Publication date: January 30, 2025Inventors: Shaofeng Ding, Qiang Liu
