title: RNA from Panagrolaimus davidi at -10 in frozen media
design: For the Illumina sequencing the nematodes were cultured in S medium at 20°C for 3 weeks and fed every 3-4 days with Escherichia coli. After acclimating at +5°C for 3 days, the samples were cooled to -10°C at 0.5°C min-1 as with Treatment 5U. When this temperature was reached samples that had frozen spontaneously during cooling were removed and labelled. The worms were snap frozen in 1.5ml microcentrifuge tubes at -80 degrees Celsius and preserved at -80 degrees Celsius until extraction. RNA was extracted from whole worms using TRI-sure (Bioline) according to manufacturer's instructions and purified on Qiagen RNeasy columns. RNA were checked for purity on standard agarose gels and quantified using a NanoDrop spectrophotometer. 5ug from 8 different treatment stages was sent for sequencing.
