RBS digestion: Revenge

HokkaidoU Japan 20100818a.JPG
Reagent Amount
1-2M 10 uL
DW 4 uL
10x M Buffer 2 uL
BSA 2 uL
Xba I 1 uL
Pst I 1 uL
Total 20 uL

->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

  • Transfered to 1.5 mL tube and frozen with liquid nitrogen
  • Melted and centrifuged at 15000 rpm, 4C for 5 min
  • Transfered supernatant to another tube
    • Driven by precaution centrifuged the supernatant and discarded it's supernatant
  • Rinsed the tube walls with 100 uL of 70% Ethanol and centrifuged at 15000 rpm, 4C for 5 min
  • Discarded the supertenant and dried via vacuum desiccator
  • Melted in 5 uL of TE

Electrophoresis

Electrophoresis after Ethanol presipication
  • Added 1 uL of 6x SB to DNA Solution of 1 uL
  • Did the same to supernatant　retreaved for precaution
Lane DNA
2 TSUDA Marker 1
3 supernatant
4 DNA solution
  • DNA solution band is visible
    • Looks OK
