20.109(S14):Data analysis (Day7)

Introduction

Topic 1: document some of the lecture info on NHEJ key players, leading to

Topic 2: more about C401 inhibitor, and

Topic 3: more about colony-forming assay and staining approach

Topic 4: but the most interesting/fun will be flow analysis: mean vs median choice; breaking down the Day 5 equation a bit more

Oh, and just a word about the MCS/GC/etc. issue for context

Protocols

Part 1: Stain irradiated cell colonies

Option to do it on M3D1 if they want to grow longer for bigger colonies?

All in main lab: rinse w/ 2mL pre-warmed PBS, add 2 mL Coomassie for 1 hr w/shaking, save it afterward, rinse w/PBS again, let dry a little bit, then count colonies right away. (Suggestions for counting approach and how to decide which ones pass the threshold.)

Part 2: Flow cytometry analysis

Save-as Excel sheet, keep just what they need.

Prepare separate sheet with columns/calculations of interest.

Finally, copy in the data.

Add all B/G ratios and NHEJ ratios group Excel worksheet somehow?

For next time

Methods, as promised.
