2. Purification of pAct5C DNA and pGaTB DNA
pAct5C DNA and pGaTB DNA was purified from E. coli prepared on 8/29by QIA prep Spin Miniprep Kit.

September 1st


1. Agarose gel electrophoresis of PCR produsts and the purified pAct5C DNA and pGaTB DNA
Agarose gel image is shown below. Left to right: HS promoter 10uL, UAS fragment 10uL, pAct5C DNA-1, pGaTB DNA-1, pGaTB DNA-2, pAct5C DNA



2. Expected bands for pAct5C DNA and pGaTB DNA were detected on the gel, but band for UAS fragment was not.

September 3rd


1. PCR amplification of DNA fragments containing GAL4, Act5C promoter and LacZ sequence
pGaTBDNA was used as a template to amplify GAL4 sequence. pAct5C-LacZ DNA was used to amplify Act5C promoter-enhancer region and LacZ.
