1 - Electrophoresis of the digestion of BBa_K1155001, BBa_K1155002, BphR2 in pSB1C3

Anaïs, Zhou

  • BBa_K1155001 :
Psgel21607.jpg
  • Well 1 to 5 : 2µL BBa_K1155001 digested by EcoRI/PstI+2µl of 6X loading dye
  • Well 6 and 7 : 2µL BBa_K1155001 digested by SacII+2µl of 6X loading dye
  • Well 8 : 6µL DNA Ladder
  • Gel : 1.2%

Expected size :

  • BBa_K1155001 digested by EcoRI/PstI : 2037bp + 333bp
  • BBa_K1155001 digested by SacII : 2370bp

We obtain fragment at the right size. We will amplify BBa_K1155001.

  • BBa_K1155002 :
Psgel31607.jpg
  • Well 1 to 8 : 2µL BBa_K1155002 digested by EcoRI/PstI+2µl of 6X loading dye
  • Well 9 : 6µL DNA Ladder
  • Well 10 to 17 : 2µL BBa_K1155002 digested by SacII+2µl of 6X loading dye
  • Gel : 1.5%

We didn't obtain fragments at the right size. We will do the ligation again.

Psgel41607.jpg
  • Well 1 to 8 : 2µL BphR2 in pSB1C3 digested by EcoRI/PstI+2µl of 6X loading dye
  • Well 9 : 6µL DNA Ladder
  • Well 10 to 17 : 2µL BphR2 in pSB1C3 digested by SacII+2µl of 6X loading dye
  • Gel : 1.5%

We didn't obtain fragments at the right size. After reading the sequence again, we find an digestion site in the middle of our biobrick. We will do a Gibson assembly to modify this site.
