Building a Reporter Gene to Determine Chromatin Protein Function (Ligation into the mammalian vector)
- Ligation of construct BD001(KAH182-KAH201) and mammalian vector V0200 and cloning in Bl21-DE3, The new construct is named: BD002.
- KAH182 = BBa_S04739 and KAH201 = BBa_S04745 and V0200 = BBa_J176121.
- Assembly strategy: The backbone V0200(N/S)/4442 , the insert is BD001 (KAH182-KAH201) (N/S)/1901.
