  • Erythrocytic cells and method for loading solutes
    Publication number: 20070105220
    Abstract: A dehydrated composition is provided that includes freeze-dried erythrocytic cells. The invention further provides methods for loading a solute into a cell comprising disposing a cell in a solution having a solute concentration of sufficient magnitude to produce hyperosmotic pressure on the cell for transferring a solute from the solution into cell.
    Type: Application
    Filed: August 6, 2004
    Publication date: May 10, 2007
    Applicant: The Regents of the University of California

  • Method for eliminating fragile cells from stored cells
    Publication number: 20050032031
    Abstract: A method for reducing hemolysis in cells including washing cells in a solute solution having the capabilities of reducing cell hemolysis by at least about 0.50% for each 100 mOsm increase in osmolarity of the solute solution. A cell produced by the method for reducing hemolysis. The method permits removal of osmotically fragile cells from the population.

  • Cells and method for preserving cells
    Publication number: 20050031596
    Abstract: A dehydrated composition is provided that includes freeze-dried cells. A method for loading a solute into a cell comprising disposing a cell in a solution having at temperature of at least 25° C. and a solute concentration of sufficient magnitude to produce hyperosmotic pressure on the cell for transferring a solute from the solution into the cell. A method for reconstituting dried cells by drying loaded cells in a drying solution and reconstituting dried cells in a rehydration solution. A method for stabilizing cells by producing cells having an effective amount of a solute and a mean corpuscular hemoglobin greater than about 10.

  • Cells and improved method for preserving cells
    Publication number: 20050031597
    Abstract: A method for maintaining a viability level of a metabolite in a biological sample comprising disposing a biological sample into a solute solution comprising a solute and a chemical selected from the group consisting of a monosaccharide, a monosaccharide polyol, a cell metabolite-controlling agent, a salt, and mixtures thereof; and incubating the biological sample in the solute solution while maintaining a viability level of a metabolite in the biological sample.
