Flies expressing Zzzz\aptamerhs.pepC2.T:Ecol\trxA using cyclic heat shock from the third larval instar until eclosion generally do not have eye defects, although some lines carrying Zzzz\aptamerhs.pepC2.T:Ecol\trxA do show a higher frequency of rough eye phenotypes than control lines.
Used as a control in experiments studying the effects of aptamers which bind cdc2 or cdc2c proteins in transgenic flies.
