cDNA Synthesis in Atlas cDNA Expression Array

[Yoonsuk Park]

Hi, everyone,

Currently, I'm trying to use Atlas cDNA Expression Array.  However, I have
a really frustrating problem in cDNA synthesis. I cannot get
[P-32]-labelled cDNA.  Even, it didn't work the control poly-A+ RNA in
the kit, either.  What I got after column chromatography had very low
radioactivity, compared to 1-5 million cpm indicated on the manual.  I
have tried the new reverse transcriptase which Clontech newly provided
after the first frustration.  And, I have done everything the tech support
suggested without any success.
Is there anyone who can give me some advices?
I would appreciate receiving any tip.
