  • Patent number: 10745814
    Abstract: The present disclosure provides methods of activating an enzyme, such as error prone or template independent polymerase, using electricity to alter pH of a reaction zone and reaction site from an inactivating pH at which the enzyme is inactive to an activating pH at which the enzyme is active to add a nucleotide to an initiator or growing polymer chain. The activating pH can then be changed back to an inactivating pH and the process repeated as many times as desired to produce a target nucleic acid sequence.

  • Publication number: 20200190550
    Abstract: Methods for making a polynucleotide is provided. The methods include (a) providing a first single stranded oligonucleotide, (b) providing a second single stranded oligonucleotide under conditions wherein the first single stranded oligonucleotide anneals to the second single stranded oligonucleotide thereby forming a double stranded oligonucleotide template having an extendible end comprising the 3? terminal nucleotide of the first single stranded oligonucleotide, (c) providing a reaction mixture to the double stranded initiator wherein the reaction mixture comprises an enzyme, a selected nucleotide triphosphate, and divalent cations, and wherein the enzyme extends the extendible end, (d) regenerating an extendible end of the extended template, and repeating steps (c) to (d) until a polynucleotide of a desired sequence or information content is formed, with the proviso that step (d) is not required to be performed after the polynucleotide is formed.

  • Publication number: 20110287947
    Abstract: Disclosed are methods and systems for determining the three-dimensional structure of chromatin in eukaryotic cells. More specifically, disclosed are methods and systems for obtaining chromatin structural information by surface immobilization, i.e tethering crosslinked protein:DNA complexes and/or ligated DNA complexes to media such as beads, gels, and or matrices during the conformation capture assay. In general, the method includes contacting a cell with a cross-linking reagent to cross-link DNA and protein in the cell; lysing the cell, producing cross-linked protein:DNA complexes by cutting the chromatin using a chemical, physical or enzymatic method, substantially immobilizing the cross-linked protein:DNA complexes, ligating the cross-linked protein:DNA complexes intramolecularly such that the ligated protein:DNA complexes represent structural organization of the chromatin; characterizing the ligated DNA by sequencing or other methods; and identifying any structural organization of the chromatin.
