Materials and Methods First-strand cDNA Synthesis Total RNAs extracted from your samples were used for the synthesis of first-strand cDNAs by reverse transcriptase. Reverse transcription was performed for 1.5 h at 42ºC in a final reaction volume of 20 ㎕ containing 3 ㎍ of the purified total RNA, 4 ㎕ of 5 reaction buffer (Promega, Madison, WI, USA), 5 ㎕ of dNTPs (each 2 mM), 2 ㎕ of 10 μM dT-ACP1 (5’-CGTGAATGCTGCGACTACGATIIIIIT(18)-3’), 0.5 ㎕ of RNasin RNase Inhibitor (40 U/ ㎕; Promega), and 1 ㎕ of Moloney murine leukemia virus reverse transcriptase (200 U/ ㎕; Promega). First-strand cDNAs were diluted by the addition of 80 ㎕ of ultra-purified water for the GeneFishingTM PCR, and stored at -20ºC until use. ACP-based GeneFishingTM PCR Differentially expressed genes were screened by ACP-based PCR method (Kim et al., 2004) using the GeneFishingTM DEG kits (Seegene, Seoul, South Korea). Briefly, second-strand cDNA synthesis was conducted at 50ºC during one cycle of first-stage PCR in a final reaction volume of 20 ㎕ containing 3-5 ㎕ (about 50 ng) of diluted first-strand cDNA, 1 ㎕ of dT-ACP2 (10 μM), 1 ㎕ of 10 μM arbitrary ACP, and 10 ㎕ of 2 Master Mix (Seegene). The PCR protocol for second-strand synthesis was one cycle at 94ºC for 1 min, followed by 50ºC for 3 min, and 72ºC for 1 min. After second-strand DNA synthesis was completed, the second-stage PCR amplification protocol was 40 cycles of 94ºC for 40 s, followed by 65ºC for 40 s, 72ºC for 40 s, followed by a 5 min final extension at 72ºC. The amplified PCR products were separated in 2% agarose gel stained with ethidium bromide. www.seegene.com
