To make the working stock of the primers.
- 90 ul of Nuclease free (or Nanopure) H20 to 1.5 ml tube
- 10 ul of Stock primers
- Vortex briefly
I made these carefully in order to produce the following 12 pairs of primers.

After producing the working stocks I then made a 10 reaction master mix.

Protocol:
- Added Ssofast to each of 12 tubes

- Carefully added FWD primer, then Reverse primer to the appropriate tube
- Vortex briefly
- One Master Mix used per column in plate
- Pipette 19 ul of master mix to each well for the appropriate column
- Either No Template Control (NTC) or sample for each Row in the plate
- 1 ul Sample/NTC per well in the appropriate row

There was some very interesting results.
CARM1, BMP2, HSP11b, and PGE/EP4 All showed down regulation from heat shock in all populations.
GDF-8 Had High expression in Fidalgo
CRAF1 had Up regulation in the Oyster Bay population and down regulation in others
PGRP-S had Up regulation in the Dabob population and down regulation in the others
TLR2.1 Had the most interesting response. It was down regulated in the Fidalgo bay population, Equal Expression in the Oyster Bay population, and did not amplify in either Dabob sample.
HSP70b, GRF-78, NFKBina and GDF-8b had severe issues with the melt curve and odd expression in the samples. These four primers are probably not useful.
I'm testing the next batch of primers now and will report the results when the come in.
You can see the raw qPCR file here.
Nice work cranking through these!
ReplyDeleteA couple of quick notes:
- Please write down the SR IDs of the primers. This will ensure that everyone knows precisely which primers you're using. We've had issues in the past with same/similar primer names for genes and people not knowing which primers were actually used.
- Although fun to start thinking about, you can't really "analyze" this data to gain any insight into the implications. This is due to a couple of factors. The first is that you're only looking at a sample size of n=1. Additionally, you still have to normalize the expression to actin (and/or other genes you determine that have stable expression levels across treatments/individuals). Seeing that your actin expression appears to be highly variable, the rough analysis above is probably meaningless at this point. So, no need to spend time comparing expression levels across treatments/populations at this stage of the game.
