I’ve been asked to isolate RNA from some paraffin-embedded Olympia oyster gonad tissue.
Despite some excellent documentation by Laura Spencer (images of tissue layouts in histology cassettes and a corresponding cassette mapping key file), the histology facility seems to have flipped some things around and/or repositioned/split the contents of each cassette. This makes ID-ing the proper tissues tedious and, at times, difficult.
The list of tissues that needs to be processed is listed in this GitHub Issue #648. I’ve also added the list below:
NF-10 22 NF-10-23 NF-10-24 NF-10-26 NF-10-28 NF-10-30 SN-10-16 SN-10-17 SN-10-20 SN-10-25 SN-10-26 SN-10-31
Prior to beginning RNA isolations, I have annotated images of the histology blocks and will be waiting for Laura to confirm that my annotations are correct. I will be posting a link to this notebook entry in the GitHub issue listed above for her to view and wait for her confirmation.
UPDATE 201700707 - Laura has indicated that many of my annotations are incorrect. Katie has gone through and made proper identification: https://github.com/sr320/LabDocs/issues/648#issuecomment-313792588
Additionally, as indicated in the GitHub Issue above, histology block “Oly 14” does not have a corresponding tissue cassette photo (containing sample NF-10 26). Without the original image, I don’t think I can make an accurate guess on how the tissues are oriented in the resulting two histo blocks (see below).
