Ratiometrica-Flu: 4th attempt at PCR of fragments


  • Only vectors this time as we are still not sure if we have got the Velocity mastermix recipe right, as we are waiting for our orders of Phusion to arrive
  • Results: no bands for any lanes including positive control

Tuesday (21/08/12)

PCR of positive control


  • Our order of Phusion has arrived- though we are still not confident with our PCR so we decided to first test with sfGFP
  • Standard PCR conditions are used
  • Results: success

Ribosense: PCR for Mg Riboswitch


  • PCRs were run for pJS130.1 split vector ('+8 codons')
  • Colony PCR for endogenous Bacillus subtilis Mg Riboswitch ('+8 codons') was run
  • Gels were run for above reactions, only one band for half of the pJS130 vector was visible.

Wednesday (22/08/12)

PCR for Mg Riboswitch


  • PCRs were run for F Riboswitch from Yale's plasmid with overhangs for standard assembly.
  • Colony PCR for endogenous Bacillus subtilis Mg Riboswitch (both '+8 codons' and '-8 codons' versions) were re-run.
  • Gels were run for above reactions, only one band for positive control was visible.


Cells cultured for Miller assay


  • B. subtilis strains carrying F riboswitch and 'KO' strains cultured separately in LB and 5µg/mL Chloramphenicol at 37°C
  • E.Coli carrying F riboswitch cultured in LB and 50mg/ml Ampicillin at 37°C

Thursday (23/08/12)

  • Miller assay set up and running with the wild type and crcB knock-out Bacillus strains and an E. coli strain which contains the construct on an episomal plasmid.
