A - The frame coli Odor free
PCR
by Romain
Strains used: E. coli MG1655Z1 and E. coli MG1655, and oligonucleotides used: FTR-Apra-F and FTR-Apra-R.
Protocol:
- 218µl of H20 MilliQ
- 80µl GoTaq buffer 5X
- 16µl oligonucleotide FTR-Apra-F (10mM)
- 16µl oligonucleotide FTR-Apra-R (10mM)
- 12µl DMSO 10mM
- 32µl MgCl2 (25mM)
- 8µl dNTP (10mM)
- 2µl of GoTaq enzyme
- 2µl of different bacterial cultures in each tubes:
- Tube 1: MG1655Z1 10I
- Tube 2: MG1655 100II
- Tube 3: MG1655 50I
- Tube 4: MG1655 100I
- Tube 5: MG1655Z1 10II
- Tube 6: MG1655 50II
- Tube 7: MG1655Z1 10I positive control with plasmid
Results of the PCR: The electrophoresis revealed nothing
New PCR with different enyme.
Strains used: MG1655 and MG1655Z1, and oligonucleotides used: FTR-Apra-F and FTR-Apra-R.
