Samples were run following kit protocol: * Chip priming station in Position C with syringe clip at top position * RNA denatured at 70C for 2mins and stored on ice. * RNA ladder aliquot was from 20160826 by Hollie Putnam. * * * # RESULTS Bioanalyzer data file (XAD): * [Eukaryote Total RNA Pico_2018-08-01_11-45-07.xad](https://owl.fish.washington.edu/Athaliana/20180801_bioanalyzer_crab_RNA/Eukaryote%20Total%20RNA%20Pico_2018-08-01_11-45-07.xad) ELECTROPHEROGRAMS: ![](https://owl.fish.washington.edu/Athaliana/20180801_bioanalyzer_crab_RNA/20180801_bioanalyzer_crab_electropherogram.jpg) * * * GEL REPRESENATATIONS ![](https://owl.fish.washington.edu/Athaliana/20180801_bioanalyzer_crab_RNA/20180801_bioanalyzer_crab_gel.jpg) * * * These results look great to me. Clear, defined peaks/bands, representing ribosomal RNA. Oddly, one sample (crab_506) appears to be shifted, relative to the other three, despite exhibiting the same peak/banding pattern. Not sure what would cause something like this; contaminants? Regardless, we finally have clean RNA and have a usable Bioanalyzer profile to use for reference for crab RNA. NOTE: The lanes marked with red on the gel representation image indicate that a ribosomal integrity number (RIN) could not be calculated. This is to be expected! The RIN is based on the expectation of two rRNA bands. The anomaly is sample crab_451 - a RIN was actually determined for that sample! Will likely move forward with additional RNA isolations using the RNeasy Plus Kit (Qiagen).
