I tried the "5'-Amplifinder RACE Kit" from Clontech. It was a complete 
failure. Even the supplied control was very poor. Other controls showed, 
that the reverse transcription step worked. Therefore I think anchor 
ligation using T4 RNA Ligase is the problem. Could it be that Clontech's T4 
RNA Ligase is trash?
