Flies expressing Zzzz\aptamerhs.pepCa.T:Ecol\trxA,T:nls3 using cyclic heat shock from the third larval instar until eclosion generally do not have eye defects, although some lines carrying Zzzz\aptamerhs.pepCa.T:Ecol\trxA,T:nls3 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.
