Building a Reporter Gene to Determine Chromatin Protein Function

  • Ligation of KAH182 = BBa_S04739 and KAH201 = BBa_S04745 and cloning in DH5α-T.
  • Assembly strategy: The backbone KAH201(S/P)/3403 , the insert is KAH182(X/P)/1675.


  • Ligations
Ligation
1. E. coli DH5α-T KAH182(X/P)/size, 15.85 ng + KAH201(S/P)/size, 36.29ng KAH182/KAH201 2:1 No Colonies
2. E. coli DH5α-T KAH182(X/P)/size, 15.85 ng + KAH201(S/P)/size, 36.29ng KAH182/KAH201 3:1 No Colonies 3:1 1 Colony
3. E. coli DH5α-T KAH182(X/P)/size, 15.85 ng + KAH201(S/P)/size, 36.29ng KAH182/KAH201 4:1 Two Colonies
4. KAH201(S/P)/size, 36.29ng (Control Plate)
  • Calculations are for the ng of insert we need to get a 2:1, 3:1 and 4:1 ratios of insert molecules to 50 ng vector molecules
  1 (2:1) 2 (3:1) 3 (4:1) 4 (- Ctrl)
Insert DNA 3.11 4.66 6.21 ---
Vector DNA 1.37 1.37 1.37 1.37
2x lgn buf (Roche) 5.48 7.03 8.58 5.0
T4 ligase (NEB) 1.0 1.0 1.0 1.0

  10.96 μL 14.06 μL 17.16μl 10μL
  • The incubation time for the ligation process was 30min at room temperature.
  • Fast transformation, 30 min on ice.
