Info

The red Low Read II samples were renormalized via pooling and the new MC samples were added to that same pool at 1 ul per sample. This pool was then adjusted to 1nM. The pool of the repeated RMJan22 samples was also adjusted to 1 nM. 50 ul of Low Read was added to 100 ul RMJan22. However, when the LowRead pool was qPCRed, one replicate was much higher than the other 2. The 1:2 ratio might be off because of this. We are running an RNaseP plate to recheck the recalibration of the 7500 qPCR machine. We ran an RNaseP Test plate to check the recalibration of the qPCR machine and it looks good. Because the reads passing filter was so low (35%), we are going to re-qPCR new dilutions of the pools and try this again.

RNaseP Check of qPCR machine recalibration:

Recalibration looks good. The 5,000 copy samples all reported back as close to 5,000 copies and the 10,000 copy samples all reported back as roughly 10,000 copies with no real outliers. A snapshot is below:
