## For standards add 0-5 uL of glycerol standard '''(or of a 1/10 dilution of the glycerol standard)'''.
## For standards add 0-5 uL of glycerol standard.
## Add 5 uL of resuspended lipid to each well to start (also make a 5uL blank of the butanol mixture) and mix.

## Let sit for ~30 min at room temperature (or 5 min at 37C if you are in a hurry).  If using > 10 uL of butanol mixture the solution may be cloudy, let it settle and it should become more clear.
