Correlating Technical Replicates Part 10
The end of a saga
I think I’m at a point where I kind of trust my new dataset with bad samples removed. Within each peptide, all transitions show a consistent expression pattern between sites. Peptides within a protein, however, have different expression. This could be due to alternative splicing.
There are three different patterns I saw with my protein expression data:
- Puget Sound sites had similar expression values, but Willapa Bay had higher expressoin
- There’s a U-shape (CI –> FB –> PG (minimum) –> SK –> WB)
- All five expression values are similar
For my future reference, I’m going to paste my boxplots from one transition per peptide below. I’ve sorted proteins by their functions.
