  • Compositions for solubilizing cells and/or tissue
    Patent number: 9814422
    Abstract: Solubilizing compositions are provided that include a 3-(alkyl dimethyl ammonia) propane sulfonate zwitterionic surfactant and a polyethylene glycol alkyl ether nonionic surfactant, provided that the zwitterionic surfactant and the nonionic surfactant are not simultaneously and respectively 3-(decyl dimethyl ammonia) propane sulfonate and polyoxyethylene (4) lauryl ether. Also provided are methods for solubilizing cells and/or tissue of a subject in vivo and methods for recovering proteins from skin cells of a subject in vivo using the solubilizing compositions.
    Type: Grant
    Filed: March 28, 2012
    Date of Patent: November 14, 2017
    Assignees: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, DX BIOSCIENCES, INC.

  • Methods for Solubilizing Cells and/or Tissue
    Publication number: 20170105673
    Abstract: Solubilizing compositions are provided. The compositions comprise at least one zwitterionic surfactant and at least one nonionic surfactant. In one embodiment, the compositions may be useful for solubilizing and remodeling and/or removing tissue on or beneath a patient's skin, optionally in conjunction with the application of energy to a region of interest on the skin. In one embodiment, at least one analyte may be collected and analyzed from the solubilized tissue.
    Type: Application

  • COMPOSITIONS FOR SOLUBILIZING CELLS AND/OR TISSUE
    Publication number: 20150275174
    Abstract: Solubilizing compositions are provided. The compositions comprise 3-(decyl dimethyl ammonio) propane sulfonate and polyoxyethylene (4) lauryl ether. The compositions may be useful to solubilize or lyse cells and/or tissue. The compositions may be further useful to preserve and recover proteins, including cytosolic proteins, nuclear proteins, and surface proteins contained within the solubilized or lysed cells and/or tissue.
