  1. KAH109/pT7CFE1-CHis: KAH109/(E/P)/1132 + pT7CFE1-CHis/(E/P)/3600
  2. KAH111/pT7CFE1-CHis: KAH184/(E/S)/1123 + "
  3. KAH112/pT7CFE1-CHis: KAH187/(E/S)/1123 + "
  4. KAH115/pT7CFE1-CHis: KAH188/(E/S)/931 + "

  7. KAH151/pT7CFE1-CHis: KAH191/(E/S)/967 + "
  • Note: KAH109 is being re-done as an internal control to trouble-shoot the ligation
  • Note: KAH111-KAH151 are all cut and purified already

Ligations (trouble shooting suggestions)

  • Note: Use 50 ng of vector this time (instead of 20)
  • Note: Use a 3:1 ratio of insert to vector... x μL insert = 3 * (bp of insert/ bp of vector) * 50 ng vector / (concentration of insert ng/μL)
