qPCR with Actin primer set, etc.

Preparing previously sequenced larval samples

I spoke with Katherine last week about combining QuantSeq data from the previous run and the upcoming run. She advised (and I agreed) that it’s optimal for me to re-run those samples. The kits have changed slightly, in addition to me not DNasing the samples previously, her prepping the libraries etc. I have RNA in the -80, so I’m going to catch them up to the other samples today by Turbo DNasing them, and including in the qPCR re-do. Samples are: 34, 35, 37, 39, 41, 44, 45, 47.

DNA contamination re-check with Actin primer set

Today we received a new set of Actin primers that Sam had previously used to check for gDNA contamination. I tested them on one of my larval DNA samples, and voila! My positive control amplified, and the curves appear as expected.

Rather than re-doing ALL samples, I did a sub-set, as I’d like to avoid more thawing/freezing cycles. Oddly, the + control didn’t amplify again with this new primer set.

I discussed the issue with Steven and Sam. Since I did in fact DNase all my samples, I shall move ahead with the RNA concenrating and quality checking.

Quantifying remaining RNA samples after DNasing

In addition to re-running qPCR on 42 samples, I also measured [RNA] for samples that I had not yet quantified due to running out of Qubit tubes. The samples that I did qPCR on were mostly those that also needed quantifying (to minimize freeze/thaw), however I also did some other samples to include a random assortment.

Next step: concentrate dilute samples with Zymo Cleaner/Concentrator

The QuantSeq prep starts with up to 500 ng RNA in 5uL (or less). Katherine advised that I should use no less than 200 or 300 ng. So, here is how much RNA I have in 5 uL:
