Extrusion and DLS of new sample

  • Extrusion process went smoothly today.
  • I looked at the vesicles with DLS. NOTE: I should have saved the little beaker of PBS so I didn't have to pour more out.
  • Results were very similar to the results from the batch from Friday, surprisingly. So that means the Friday batch hadn't decayed yet I guess. Next up is to make some with 30% PG, and then add in Texas Red.
  • I want to see if I get a similar size for the part PC part PG vesicles. If I do . . . that is pretty small. I'll have to check if I can see them at all.

I did a few more tests, with similar results
