→Incubated at 37C for 60 min
- Added 4 uL of 6x Sample Buffer making it total of 12 uL per lane and electrophoresed
→Extracted for gel
→Electrophoresed 10 uL of Extracted DNA
Failure
- After better inspection of Kit specs it came to lite that retreavel rate for 50 bp and less is 26%
- RBS is just quite small when cut

エタ沈
- 2 uLの3 M 酢酸ナトリウムを加えた
- 44 uLのエタノールを加えた
- 液体窒素の中で凍らせた(1.5 mLのチューブに移す)
- 溶かしてから15,996 rpm @4℃で5分間遠心した
- 上清をほかのチューブに移した(一応これも遠心し,上清を捨て,同じ操作をした)
- 100 uLの70%エタノールで壁をリンスし,15,996 rpm @4℃で5分間遠心した
- 上清を捨て,真空デシケータで乾燥させた
- TE 5 uLで溶かした
電気泳動
- TEで溶かしたDNA Solution 1 uLに6x SB 1 uLを加えた
- 最初にとった上清も同じ操作をした
