Revision as of 12:00, 25 September 2012






September 11th


The female-virgin flies (yw) and male flies (yw) were again collected and separately kept at 25℃.

September 12th


The transfected cells were examined under the confocal lazer microscope (Olympus, Fv10i)
Results: about 20 % cells were observed to be EGFP-positive, indicating that the P-element plasmid, pUAS-EGFP-TNFAIP3 is functional in Drosophila cells. We therefore decided to microinject this DNA into Drosophila embryos to establish transgenic flies.

1-2-7 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℃.
