Slide Preparation

1. Grow overnight culture in 5ml of LB broth at 37C
2. Dilute the overnight culture to a ratio of 1:100 and incubate at 37C for 1 hour
3. Set up the following broths with different concentrations of IPTG in 5ml of LB broth:
   • 2mM IPTG
   • 0.2mM IPTG
   • 0.02mM IPTG
   • Broth only
4. Innoculate the broth with the appropriate cultures and incubate at 37°C for two hours.
5. Prepare the slides by pippeting 500 µL of 1.2% agarose. Gently place the coverslip over the slide.
6. Wait for about 5 minutes for the agarose to harden. Remove the coverslip by gently sliding the coverslip horizontally from the slide. This is to ensure that agarose layer remains undisturbed.
7. Transfer 200 µl of each sample to microfuge tubes and label accordingly. Add 0.5 µl of membrane dye to each sample.
8. Place 0.5 µl of each sample in each well of the slide and label accordingly. Place a coverslip on top of the slide.
9. The slide is now ready for microscopy.
