7 23 2015 PGE/EP4 qPCR 2

Today I ran duplicates for the targets I ran last week. I'm hoping to get strong replicates for analysis. Here I ran the PGE/EP4 which last week had issues with the NTC.

The curves look good with no amplification in the NTCs. To check this run compared to the previous one, I pulled the Ct values and graphed them against one another.

The reps dont look great with alot of the second reps samples failing to amplify. I'm not sure what's causing these huge numbers of failures with the data. I'll probably need to rerun this on the CFX machine.

You can see the raw data here.
