5. PCR amplification of GAL4
Reaction conditions
6. PCR products were applied to the agarose gel electrophoresis as shown below. 
7. pSB1C3 and UAS fragments were ligated in the following reactions.
The following reaction were carried out as a negative control.
8. 7 ligation products were transformed into E. coli XL-1 Blue and spread on the LB Chloramphenicol(＋) plate and incubated at 37℃ for 16 hours. September 10thAt 20 min after removing the medium, 25 uL of serum free medium containing the 1 uL of siLentfect and 200 ng each of pAct5C-GAL4 DNA and pUAS-EGFP-TNFAIP3 DNA was added to the well. At 4 hours after transfection, the transfection medium was removed and the Schneider’s Drosophila medium containing 10% fetal bovine serum was added to each well. The cells were incubated for 48 hours at 25 ℃. 1. Single colony isolation of ligationproducts Ligation product prepared on 9/9 (UAS and pSB1C3) gave us some colonies and negative control sample gave us no colony. We therefore picked up four independent colonies and cultured them in 2.5mL LB Chloramphenicol (＋) medium at 37℃ for 16 hours. 2. Digestion of HS promoter fragment and Act5C promoter with XbaⅠ and BamHⅠ DNA fragments carrying HS promoter (prepared on 9/5) and those carrying Act5C promoter (prepared on 9/3) were digested with XbaⅠ and BamHⅠ.
Digested fragments were purified from the gel by QIA quick Gel Extraction Kit. Photo of agarose gel 
3. PCR amplification of GAL4 fragments We tried PCR under four different conditions described below.
