Abstract:
Thirty-five human ovarian cancer tumor specimens were frozen by both rapid freeze and slow freeze with dimethyl sulfoxide (DMSO) to determine which method results in optimal postthaw viability. Median viability following a rapid freeze was 8% as compared to 90% with slow freeze with DMSO (P = .0001). Eighty-seven percent of tumors had a viability of > 80% following slow freeze with DMSO. When experimentation on human ovarian cancer tumor cells requires postthaw viability, we recommend slow freeze with DMSO.
