Extraction notes

  • POR samples: pulled out 150ul of shield from the original sample tube, and added that to a new 1.5ml tube containing 150ul of new RNA/DNA shield
  • Spun down samples for 3 minutes at 9000 rcf and then transfer the supernatant to new tube without disturbing the pellet
  • 300ul of shield, 15ul of ProK, and 30ul of ProK digestion buffer, let sit for 2 minutes
  • All spins were done for 1 minute or 2.30 minutes
  • Did two washes with 700ul of wash buffer for both the DNA and RNA
  • Then followed the protocol as described in protocol

Qubit

  • Used Broad range dsDNA and RNA Qubit Protocol
  • All samples read twice, standard only read once

Tape Station

  • Samples not analyzed

Gel

  • Modified from this protocol
  • Added 0.75g of agarose and 50ml of 1x TAE to flask and microwaved for 45 seconds. This makes a 1.5% gel
  • Once cool enough to touch added 2ul of gel green stain
  • Swirled and poured into gel mould with comb
  • Once solidified, covered with 1X TAE as a running buffer
  • Added 1ul of purple loading dye to each of my QC strip tube samples. I had ~9ul of DNA leftover from QC and ~8ul of RNA
  • Loaded my gel with the DNA first, then skipped a well and then the RNA
  • Ran the gel for 60 minutes at 60 volts 20210913_gel.jpg

Addtional Notes

  • Nearly all RNA elute had some pigment. The RNA spin columns were also pigmented.
