8 10 2015 EF1d Mech Stress 2 rep qPCR

Today I ran mechanical stress samples in replicates of two to generate data about expression values. Here I ran EF1d . I ran NTCs on a separate plate using the same reaction volume and 9 ul of PCR water.

The amplification and melt curves look good. There's nothing in the NTCs. I added the replicates to the comparison spreadsheet. You can see the absolute value difference between the replicates.

There are 17 samples with a greater than 1 ct difference. This entire run needs to be re run to improve replicates
