Today I did another round of Day 9 infected (12) and uninfected (12) tanner crab hemolymph RNA extractions. I also ran 2ul of the eluted 15ul RNA on Qubit. Results and details in post.

RNA extraction

I followed yesterday’s (post) extraction process as exactly as I personally could. Nothing went wrong as far as I’m aware…

Some notes:

The following tubes had small amounts of initial pelleted hemolymph:
71, 67, 177, and 44

img

The following tubes had white crystal-y stuff in them after sample preparation step:
20, 54, 24, 169, 29

img

After Step 2 (running ethanol through Zymo yellow column), tubes 44 and 29 didn’t fully run through, so I ran them through the centrifuge one more time at 10,000 g for 30 sec.

I saved the DNA again, and put with yesterday’s saved DNA in FTR 209, -20C on the labeled tube rack.

Results

Just like with yesterday’s batch of extracted RNA, I ran 2ul of each sample on Qubit with RNA HS kit.

23/24 tubes had detectable RNA!!!! WOOOOOO!!!

Samples are in -80 along with the extracted samples from yesterday (Rack 7, column 3, row 4)

The remaining pelleted hemolymph are in the same box as yesterday’s (Rack 8, column 3, row 5)

Next steps:

On Monday, I’d like to run these samples on the bioanalyzer and/or Nanodrop to make sure that things look good.
