  • Patent number: 8546145
    Abstract: The invention relates to a method of fast identification and isolation of cells featuring a desired phenotype. The phenotype is coupled to the amount of gas-liberating enzymes or increased growth. The cells are encapsulated into microcapsules allowing exchange of solvents through the microcapsule wall, but retaining some or all of the gas formed by gas-liberating enzymes on contact with corresponding substrates. Microcapsules containing increased amounts of gas-liberating enzymes are starting to float and can be separated. The cells are then isolated from the microcapsules according to standard procedures.
