C Probe SOD1/VIM Test
On Andrew's advice I'm also going to do another test using mouse cells (and human cells), this time with C-probes. To test more than one variable, I'm also going to use SOD1 and VIM. Below I've included the BLAST results testing the human probes against the mouse genome and transcriptome. VIM PA actually has a near-perfect match, but VIM PB does not match anywhere near VIM PA, so both probes should be unable to bind.
