  • Morning:
    • Choon Kit, Hung: digestion of BBa_B0015 terminator and E7 plasmid with SpeI and XbaI.
BBa_B0015 Terminator E7
DNA 5 30
Buffer 2 1 4
BSA 0.1 0.4
SpeI 1.5 1.5
XbaI 1.5 1.5
H2O 0.9 2.6
Total 10 ul 40 ul
  • Chin Chong & Darius
    • Prepare new stock for Ecoli cells containing Laci-GFP
    • Auto-clave the tips and LB broth
    • Re-run PCR for E7-imm to produce more stock for further use
    • Carry out LacI-GFP characterization with varying concentration using a fluorescence mutiplate reader (96 well)
      • 2 range of IPTG/lactose were investigated over 4 hours
      • 1st range 0-2 mM in 0.2mM increments
      • 2nd range 0-10 mM in 2mM increments
    • Results from the lacI-GFP characterization shows that there is an increasing trend in GFP fluorescence for all samples
    • Wells containing higher concentration of IPTG and lactose seems to have a higher fluorescence reading
    • Effective range of IPTG should be from 0-2 mM. As readings from 4 to 10 mM appears to be similar.
