Publication number: 20170241947Abstract: Molecular species that are immobilized in discrete locations on a planar support such as protein bands on a gel or a blotting membrane or species applied in dots or spots on a membrane are reacted with binding reagents that are applied through a porous hydrophilic transfer sheet placed over the planar support, the sheet having at least one region that is laterally bordered by a barrier with the binding reagent retained within the bordered region. The bordered region is placed directly over an area on the planar support where the molecular species are expected to reside if they are present on the support. The binding reagent is then delivered into the support to contact the species. Targeted delivery of the binding reagent is thus achieved with improved efficiency.Type: ApplicationFiled: February 13, 2017Publication date: August 24, 2017Inventors: Clayton T.

Publication number: 20170241948Abstract: This disclosure provides chips, systems and methods for sequencing a nucleic acid sample. Tagged nucleotides are provided into a reaction chamber comprising a nanopore in a membrane. An individual tagged nucleotide of the tagged nucleotides can contain a tag coupled to a nucleotide, which tag is detectable with the aid of the nanopore. Next, an individual tagged nucleotide of the tagged nucleotides can be incorporated into a growing strand complementary to a single stranded nucleic acid molecule derived from the nucleic acid sample. With the aid of the nanopore, a tag associated with the individual tagged nucleotide can be detected upon incorporation of the individual tagged nucleotide. The tag can be detected with the aid of the nanopore when the tag is released from the nucleotide.Type: ApplicationFiled: March 3, 2017Publication date: August 24, 2017Applicants: The Trustees of Columbia University in the City of New York, Genia Technologies, Inc.Inventors: Sergey Kalachikov, Jingyue Ju, Irina Morozova, Michael Dorwart
