cDNA synthesis and LOXO-101 clinical trial cDNA-AFLP analysis were performed for the 10 replicates. First-strand cDNA was synthesised from 2 μg of total RNA using a SuperScript III First Strand Synthesis System (Invitrogen, USA) in accordance with the manufacturer’s instructions. Second-strand cDNA was sythesised by adding the first-strand
cDNA reaction to a reaction mix that contained 4SC-202 cost 15 μl of 10 × cDNAII buffer, 35 U DNA of Polymerase I (Invitrogen), 3 U of RNase H (Invitrogen), and 1 μl dNTPs (25 mM) in a final volume of 150 μl, and incubating for 2 h at 16°C (). The resulting double-stranded cDNA was purified in accordance with the method of Powell and Gannon [34]. The concentration of the cDNAs was determined using spectrophotometer (Bio-Rad) and their quality was determined by electrophoresis on a 1.2% agarose gel. cDNA- AFLP A 500-ng aliquot of double-stranded cDNA was used for AFLP analysis as described by Bachem et al. [35] with the following modifications. The template for cDNA-AFLP was digested with the restriction enzymes, EcoR I/Mse I and Psu I/Mse I (Invitrogen). The Sequence of the primers and adapters used for the AFLP reactions are given in Additional File 2. AFLP reactions were performed in accordance with Bachem et al. [36]. Selective amplification products
were separated on a 10% polyacrylamide gel and stained with silver nitrate [37]. The gels were dried oxyclozanide onto 3 MM Whatman paper. Cloning, sequencing and bioinformatic characterisation To select DE-TDFs, the profiles AICAR cost of infected and non-infected samples were compared between replicates. TDFs that differed in abundance between the two types of sample, namely infected and non-infected plants, were selected only when the same pattern was observed in all replicates. The cloning of bands of interest was performed as previously described[38]. Briefly, the bands were excised from the gels using a razor blase. Each gel slice was incubated
in 10 μl of distilled water for 10 min at 96°C. Aliquots of the eluent were subjected to PCR using the same conditions as for the selective PCR described before. PCR products were separated on 10% polyacrylamide gel to confirm that the correct polymorphic fragments had been selected [39]. After verification, the recovered products re-amplified using primer pair E-0/M-0 and P-0/M-0 to provide sufficient DNA for cloning. The purified PCR products were cloned into the pGEM-T Easy vector (Promega) and then sequenced. The sequences were compared with those in the non-redundant databases of the National Center for Biotechnology Information (NCBI; http://www.ncbi.nlm.nih.gov/BLAST/) and The Arabidopsis Information Resource (TAIR; http://www.arabidopsis.
