Talk:20.109(F13): Mod 1 Day 7 FACS analysis

Schedule

Sign up for a time to do flow cytometry in the table below. Please arrive at the time you choose and then expect to spend about 45 minutes in TC and another 45 minutes at FACS. TWO or THREE teams should sign up for each time slot.

T/R

Time block	Team 1	Team 2	Team 3
I: 1-2:30 pm	Blue	Platinum	White
II: 2-3:30-pm	Purple	Yellow	Green
III: 3-4:30 pm	Orange	Pink	Red

W/F

Time block	Team 1	Team 2	(Team 3)
I: 1-2:30 pm	Red Team	Orange Team	White Team
II: 2-3:30-pm	Pink Team	Blue Team
III: 3-4:30 pm	Purple Team	Green Team

Data Summary

Key general notes about experiment

• Difference between T/R and W/F samples
  • On T/R, plain media wells were exchanged to fresh media, while wells with DMSO or C401 just stayed in the same media.
  • On W/F, all three types of media were available and exchanged to fresh before transfection.
• Collection time consideration
  • As discussed with most groups, we collected at a high flowrate in order to test many samples.
  • The downside is that transient fluctuations in the data can have a big influence, and may not be averaged out.
  • Keep this trade-off in mind as you look at personal duplicates as well as class-wide data.

Reported data

To aid class-wide comparisons (and statistics!), please post the requested information in the table below in a timely fashion using three significant digits (ex. 3.72). For samples done in duplicate, please separate the two values with a semi-colon. Once you've completed your statistics, don't get over-excited with the number of significant figures you report! For example, "3.7" will suffice. Please describe the ratio test condition in the form "0.2 ug D5 and 0.05 ug CUT D3."

• Team Example: 5000

Team Platinum observations: Compared to cells transfected with delta 5 & uncut delta 3, there was more fluorescence in the delta 5 & cut delta 3 sample, and even more in our ratio test of 1 delta 5: 3 delta 3. Compared to the delta 5, delta 3, & DMSO sample, there was less fluorescence in the sample with inhibitor.

Team Yellow observations: There was a significant increase in EGFP fluorescence between ∆5 & cut ∆3 (about 12%) versus ∆5 & uncut ∆3 (about %2). For the samples of ratio 1:3, ∆5:cut ∆3, we observed a higher amount of fluorescence than in the 1:1 experimental samples, although there was some variability between the duplicates. DMSO by itself as a solvent did not seem to have an effect on the fluorescence, but the sample with ∆5, cut ∆3, DMSO + C401 inhibitor had lower EGFP fluorescence than the equivalent samples without inhibitor.
