[Effect of natural killer cell line NK-92 against human ovarian carcinoma cells in vitro and in vivo].

Objective: To study the cytotoxic activity of NK-92 cells irradiated against human ovarian cancer.

Methods: NK-92 cells were exposed to different doses of radiation and assayed for proliferation by a standard (3)H-thymidine incorporation assay and cell count by using trypan blue exclusion. The cytotoxic activity of NK-92 cells against targets was measured in a standard (51)Cr-release assay in vitro.
