  2. Add three sterile glass beads to cell culture tube. Tighten cap. Vortex vigorously behind shield for 30 seconds. Examine microscopically to ensure that cells have been disrupted and removed from glass surface.
  3. Add cells and medium to freezer tube. Snap freeze by swirling the tube in a slurry of dry ice and acetone, d. Store at-70° C.
  4. CMV and VZV: Use tubes showing a3+ CPE. Harvest as above except add 10% DMSO and glass beads. For example, add 0.2 mL of DMSO to 2 mL of medium in cell culture tube. Mix and proceed as described above.
