Chin Chong, Zhen Fu

  • 2:30pm:

Proceed with the characterization experiment

  1. Cells that were left to grow in the morning reached OD 1.2
  2. Centrifuge the cells at 4400 rpm and at 25 deg C
  3. Remove the LB broth and Resuspend the cells with M9 medium
  4. Introduce the cells into the 96-well
  5. Induce the cells with varying concentrations of lactose (1-10mM) in 1mM increments
  6. Did Control 1: Cells with water, Control 2: M9 medium, Control 3: Water
  7. Place the 96 well into FLx800™ Fluorescence Microplate Reader and followed the protocol as before and measure RFU for 12 hrs
