Emulsion Test-Variables
The purpose of today is to get a feel of the protocols I have with the emulsion making. I'll be using yesterday's results as a positive and a starting point. As such I'll be testing each of the components in the experiment from yesterday, stretching them both in larger and smaller concentration. I'll want to measure both droplet size and bead loading. See below for the bead loading, which will be the more important of the two variables.
Bead Loading Test
- Oil phase
- Start from yesterday's oil prep (Span80-4.5%, Tween20-0.1%, TritonX100-0.05% in mineral oil)
- Oil/aqueous mixing (adopted from Shao/Church)
- Mix 95 uL TE buffer and 5 uL magnetic beads; vortex to mix
- Mix 20 uL aqueous into 200 uL oil mixture
- Vortex for 30 seconds
- Repeat mixing to 100 uL (5 times)
- Mix with vortexer for 3 minutes
- Dilute with pure mineral oil for imaging (1:100)
- Oil/aqueous mixing (adopted from Shao/Church-adjusted for Church protocol bead concentration)
- Mix 95 uL TE buffer and 10 uL magnetic Dynabeads; vortex to mix
- Mix 20 uL aqueous into 200 uL oil mixture
- Vortex for 30 seconds
- Repeat mixing to 100 uL (5 times)
- Mix with vortexer for 3 minutes
- Dilute with pure mineral oil for imaging (1:100)

Dynabeads Results
I definitely feel more confident here, but it still isn't easy.
