We ran this protocol in our community lab last month. Two of five transformations failed until we dropped the heat shock to 42 s. Worth adding a note.

Sample temperature, measured with a thermocouple in a dummy tube of mineral oil. Plot is in the repo under docs/thermal.

Trehalose stabilisation is old but the field-deployment data is what makes this worth reading. 40 °C for six weeks is a real number.

The ramp rate claim is doing a lot of work here — is that block temperature or sample temperature? Those diverge badly above 2 °C/s with thin-wall tubes.

Off-target analysis with GUIDE-seq only tells you about the sites you could capture. I would want long-read whole-genome on at least a few animals before "no detectable" goes in a title.

The teardown is beautiful. Note the flow cell is still proprietary, so "open" has a ceiling here.
