Radioactive products were made by 30 cycles of PCR amplification of 10-μl reaction volumes containing 10-30 ng of genomic DNA, 40 ng of each primer, 200 μM each of dATP, dTTP, dGTP, and dCTP, 1 μCi α- 32P-dCTP (3,000 Ci mmol -1) and 0.5 U Taq polymerase (Perkin Elmer).
Reverse transcription was performed in the presence of 500 μM each of dATP, dCTP, and dGTP, 200 μM 5-aminoallyl-dUTP (Sigma), 300 μM dTTP, 1 × first-strand buffer, 10 mM dithiothreitol, and 400 U Superscript II (Life Technologies) in 40-μl reactions at 42°C for 3 h to overnight.
To generate labeled single-stranded cDNA target, 10 μg total RNA from rat heart or brain (Clontech, Palo Alto, CA) was reverse transcribed for 2-3 h at 42°C in the presence of 6 μg random primers (Invitrogen/Life Technologies), 1x first-strand synthesis buffer (Invitrogen/Life Technologies), 10 mM DTT, dNTP mix (25 mM dATP, 25 mM dCTP, 25 mM dGTP, 15 mM dTTP, 10 mM amino allyl-dUTP), and 200 units Superscript II reverse transcriptase (Invitrogen/Life Technologies).
Reverse transcription was started by adding dNTPs to a final concentration of 1 mM dATP and 500 μM each: dCTP, dGTP, dTTP and 5-(3-aminoallyl)-2'-deoxyuridine-5'-triophosphate, (aa-dUTP) (Sigma), with 150 units of StrataScript (Stratagene, La Jolla, CA).
The purified 5 μg aRNA was labeled with Cy3 or Cy5 by reverse transcription in a solution containing 10 μg of random hexamer, 4 μl first-strand reaction buffer, 2 μl 10 mM dithiothreitol (DTT; Gibco-BRL), 1 μl of 2 mM dATP, dGTP, dTTP and 1 mM dCTP, 1 μl SUPERase-in, (Amtion) and 200 u Superscript II reverse transcriptase (Gibco-BRL).
