  • Method for determining agent capacity to alter pH using poly dA nucleic acid switches
    Patent number: 9772336
    Abstract: Disclosed are nucleic acid-based molecular switches that respond to changes in pH. The switches may be used in DNA nanodevices. The switches may also act as sensors for measuring the pH of a sample, including cells, regions thereof, and whole organisms. The switch includes an A-motif that forms at acidic pH. Also disclosed are compositions and methods for measuring the pH of cells or regions thereof, such as vesicles, the nucleus, mitochondrial matrix, or the Golgi lumen.
    Type: Grant
    Filed: September 16, 2015
    Date of Patent: September 26, 2017
    Assignee: NATIONAL CENTER FOR BIOLOGICAL SCIENCES
    Inventors: Yamuna Krishnan, Saikat Chakraborty
