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.


Digests

Incubate at 37°C for 10 minutes.
  • Enzyme 1 for KAH182 is Xba1 and for KAH201 is Spe1.
  • Enzyme 2 for KAH182 and KAH201 is Pst1.



  1. Make the (1%) agarose glee and add 30μl of restricted vector in one well and 10 μl of ladder.
