Figure 2.

RT-PCR detection of ATAK cells serially after treatment. Untreated (negative control) or ATAK cell–treated neutropenic mice were euthanized at serial time points after treatment (4 per group). The mice were homogenized in a blender. RT-PCR targeting the Herpes Simplex Virus Thymidine Kinase (HSV TK) sequence was used to detect viable cells. A indicates ATAK; AI, irradiated ATAK.

Abbreviations: RT-PCR, reverse transcription–polymerase chain reaction; ATAK, activated transfected killer.
