Automated selection of aptamers against protein targets translated in vitro: from gene to aptamer.

abstract：:The gene-external part of the human 7S L promoter was analyzed by transcription in vitro and in vivo. Compared to the wild type promoter (-178), a -66 5'deletion mutant revealed full activity in vitro but was inefficiently transcribed in vivo. Further deletion to -37 reduced template activity to 50% in vitro and to ba...
