September 11thThe female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃.
September 12th1-2-7 Purification of the candidate pSB1C3-UAS-EGFP and pSB1C3-UAS-LacZ DNAs We purified the candidate pSB1C3-UAS-EGFP and pSB1C3-UAS-LacZ DNAs by QIA prep Spin Miniprep Kit from E. coli cultured in LB medium for 16 hours (9/11). 1-1-47 Digestion of pSB1C3-UAS DNA by Spe1 We incubated BglⅡ-digested pSB1C3-UAS (9/11) DNA with SpeⅠfor 2 hours. The reaction conditions are shown below. The female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃. Composition
The digested DNA were applied to agarose gel electrophoresis. We isolated DNA from the gel by using QIA quick Gel Extraction Kit. Photo of Agarose gel. 
1-1-48 and 2-2-6 Ligation DNA fragment carrying EGFP or LacZ was ligated into the BglII and SpeI digested pSB1C3-UAS DNA .for 1hour at 16℃. Ligation reactions are listed below.
We ligated DNA fragment carrying GAL4 and DNA fragments carrying HS promoter or Act5c promoter-enhancer to pSB1C3 DNA for 1hour at 16℃. Composition
1-1-49 and 2-2-7 Transformation of E. coli by Ligation products We did transformation of E. coli Xl-1 blue with each of ligation products. Finally, we spread them on the LB Chloramphenicol(+) plate and incubated for 16 hours at 37℃. September 13thThe female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃. 1-1-50 and 2-2-8 Isolating a single colony of E. coli carrying the candidate pSV1C3-UAS-LacZ or pSB1C3-HS-GAL4 We isolated colonies (one for pSB1C3-UAS-LacZ ,three for pSB1C3-HS-G4L4) and cultured in liquid medium(2.5ml LB Chloramphenicol(+)) at 37℃ for 16 hours. No transformed colony was detected for E. coli carrying the candidate pSB1C3-Act5C-GAL4. 1-2-8 Cut check for the candidate pSB1C3-UAS-LacZ and pSB1C3-UAS-EGFP The candidate pSB1C3-UAS-LacZ and pSB1C3-UAS-EGFP DNAs (made 9/12) were digested with EcoRⅠ/ SpeⅠ and BglⅡ, respectively. EcoRⅠand SpeⅠ
BglⅡ
Then the digested samples were applied to Agarose gel electrophoresis in the order of no cut sample, EcoRⅠ/SpeⅠ-digested sample and BglⅡ-digested sample. Result of electrophoresis 
Results: No insert DNA was detected. Therefore we were not successful for these cloning. 1-1-51, 2-1-37 and 2-2-9. Ligation Ligation of DNA fragments carrying GAL4 to pSB1C3 DNA was carried out for 2 hours at 16℃ in the reaction described below. Composition
Ligation of DNA fragments carrying G4L4 and DNA fragments carrying HS promoter or Act5c promoter-enhancer to SB1C3 DNA was carried out for 1 hours at 16℃ in the reaction described below. Composition
Ligation of DNA fragments carrying EGFP or LacZ to pSB1C3-UAS was carried out for 1 hours at 16℃ in the reaction described below.
1-1-52, 2-1-38 and 2-2-10 Transformation of E. coli by Ligation products We did transformation of E. coli Xl-1 blue with each of ligation products. Finally, we spread them on the LB Chloramphenicol(+) plate and cultured at 37℃ for 16 hours. September 14thThe adult male and virgin female flies from microinjected embryos were mated with yw virgin female flies and yw male flies, respectively. Mated flies were transferred to the new food vials in every three days to lay eggs as much as possible. The female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃. 1-1-53 and 2-1-39 Isolating a single colony of E. coli transformed with Ligation products We picked up three colonies of E. coli carrying the candidate pSB1C3-G4L4, two from the candidate pSB1C3-UAS-EGFP and three from the candidate pSB1C3-UAS-LacZ (made on 9/13), and cultured in 2.5mL LB Chloramphenicol(+) liquid medium at 37℃ for 16 hours. 1-1-54 and 2-2-11 Purification of the candidate pSB1C3-UAS-LacZ and pSB1C3-HS-GAL4 DNA The pSB1C3-UAS-LacZ DNA and pSB1C3-HS-G4L4 DNA was purified from E. coli (cultivated on 9/12) by QIA prep Spin Miniprep Kit. 1-1-55 and 2-2-12 Cut check of the candidate pSB1C3-UAS-LacZ, pSB1C3-UAS-EGFP, and pSB1C3-HS-GAL4 DNA These candidate pSB1C3-UAS-EGFP DNA (prepared on 9/12), pSB1C3-UAS-LacZ DNA (prepared on 9/12), pSB1C3-UAS-LacZ DNA (prepared on 9/14) and pSB1C3-HS-G4L4 DNA (prepared on 9/14)
Digested samples were applied to the Agarose gel electrophoresis. From the left side, Two pSB1C3-UAS-EGFP DNA isolated from independent colonies (9/12) uncut , digested two pSB1C3-UAS-EGFP DNA (9/12), pSB1C3-UAS-LacZ DNA (9/12) uncut, digested pSB1C3-UAS-LacZ DNA (9/12)cut, pSB1C3-UAS-LacZ DNA (9/14) uncut, digested pSB1C3-UAS-LacZ DNA (9/14), pSB1C3-HS-G4L4 DNA from three independent colonies (9/14) uncut, digested pSB1C3-HS-G4L4 DNA from three independent colonies (9/14) Results 
We found that pSB1C3-UAS-LacZ DNA (9/14) was successfully constructed !. This is the first one we successfully constructed as a Biobrick part. 2-2-13 Ligation Ligation of DNA fragments carrying G4L4 and those carrying HS promoter or Act5c promoter-enhancer to pSB1C3 DNA was carried out for 2 hours at 16℃ in a reaction described below.
2-2-14. Transformation of Ligation products Ligation products were transformed into E. coli XL-1 blue. September 15thThe female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃. 1-1-56. Purification of candidate plasmid DNAs We reproduced The candidate pSB1C3-UAS-LacZ DNA was purified from the three independent colonies, pSB1C3-UAS-EGFP DNA from two independent colonies, pSB1C3-G4L4 DNA from three independent colonies by QIA prep Spin Miniprep Kit. Cut check of the candidate pSB1C3-UAS-LacZ DNA, pSB1C3-UAS-EGFP DNA and pSB1C3-G4L4 DNA The candidate pSB1C3-UAS-LacZ DNA from two independent colonies, the candidate pSB1C3-UAS-EGFP DNA from two independent colonies and pSB1C3-G4L4 DNA from three independent colonies were double digested with EcoRI and SpeI. Composition
The digested samples were applied to Agarose gel electrophoresis. From the left side lane to the right, two digested candidate pSB1C3-UAS-LacZ DNA, two digested candidate pSB1C3-UAS-EGFP DNA, three digested candidate pSB1C3-G4L4 are shown. Results 
We identified the properly constructed pSB1C3-UAS-LacZ DNA, pSB1C3-UAS-EGFP DNA and pSB1C3-G4L4 DNA on the gel ! These are Biobrick parts we successfully constructed. September 16thThe adult male and virgin female flies from microinjected embryos were mated with yw virgin female flies and yw male flies, respectively. In total 83 flies from microinjected embryos were mated with yw flies. Mated flies were transferred to the new food vials in every three days to lay eggs as much as possible. 1-1-58 Preparation of Biobrick part DNAs to submit E. coli carrying the successfully constructed pSB1C3-UAS-LacZ DNA, pSB1C3-UAS-EGFP DNA and pSB1C3-G4L4 DNA were cultured for 16 hours at 37℃. September 17thThe progeny flies were inspected by dissecting microscope to look for the successfully transformed w+ red eye flies (red eye screening). However, no red eye fly was found. 1-1-59 Cut check of the Biobrick part DNAs The pSB1C3-UAS-LacZ DNA, pSB1C3-UAS-EGFP DNA and pSB1C3-G4L4 DNA were purified by QIA prep Spin Miniprep Kit.
