GVP Cluster

TODO Restrict GVP biobrick with XbaI/PstI and purify both vector and GVP fragment

TODO Restict GVP fragment and pMA-gvpL with MvaI/XhoI and purify 310bp. 2200bp, and 3300bp fragments

TODO Ligate the three fragments into the vector and transform E.coli DB3 cells

TODO Find out wath the problem is with RBS??

  • Is it one of the restriction enzymes (SpeI/PstI) failing work
  • Something wrong with biobrick in the sense that there is a red colour where none was expected (where did the RFP come from, and why is it activated so strongly)

→ From left to right: 1kB ladder, Sample Steven, SpeI/PstI control with BBa_K190017, Empty Slot, GVP (6x)
→ For GVP two fragments of ~6000bp and ~3000bp are expected, and for BBa_K190017 fragments of ~900bp and ~2000bp are expected.
  • The sample of Steven-Jelle did not contain any DNA visible on gel!
  • The GVP lanes showed the expected fragment sizes, with the addition of single cut vector at ~9000bp. The fragments were cut from the gel for purification.
  • The restriction test to check SpeI/PstI confirmed the normal funtioning of the enzymes. This makes the RBS plasmid from -80 stock less attractive, because the unwanted RFP is not located behind the RBS to be cut out!
  • To check another posibility, the stored plasmids from June were cut with SpeI/PstI and the stock plasmid was cut with EcoRI/XbaI to check if the RBS is placed infront of RBS.
