Another big day

Basically every day now is a double-header day. I am getting close to having a good sample size for our first tracer (oleic acid), I think, but there are a billion reasons to keep adding to it incrementally. I am adding some samples for our second tracer (glucose), but keeping it as a secondary priority depending on what we're able to find.

We're getting better at tracking down the long-winged crickets, but it's still fairly slow going.

We're also almost out of liquid nitrogen for flash-freezing the crickets, and are very low on 2 mL Eppendorf tubes. We have a huge bag of 15-mL Falcon tubes, which we can use as a backup, but it takes more work to flash-freeze a tube of that size.

L knew about the trick of using dry ice and methanol to snap-freeze things. Looking around online, it looks like people also use 99% isopropanol. It looks like our closest source for dry ice will be in Santa Barbara, which will be another hour-long drive in either direction. The two places I've tracked down so far aren't open on Sundays.

Time to go label some tubes.
