I have been trying to amplify the 5' end of cDNA by RT-PCR followed by dG
tailing using terminal deoxynucleotidyl transferase to add on a stretch of
G's to the 3' end of cDNA following first strand cDNA syntheis.I am then
using a dC primer and a specific reverse primer to amplify the 5' end. I have
had no success.
I am using the following tailing method:first strand cDNA + 1ul 6mM GTP + 15U
terminal deoxynucleotidyl transferase at 37oC for ~30min. Reaction terminated
by heating at 70oC for 10min.An aliquot of this is then used for second
I don't know if my tailing procedure is working?
Does anyone have experience of successful dG tailing and/or can recommend a
I'd be grateful for any tips/ suggestions as to where I'm going wrong.
