... in the mouse ( Rappolee et al., 1988 ) whereas EGFR transcripts detected by RT-PCR and Southern blotting are present from 1-cell to the early blastocyst stages ( Wiley et al., 1992 ). In the cow, transcripts for TGF-α were detected from 1-cell to the blastocyst stage ( Watson et al., 1992 ). The role...

We have developed an in vivo approach using a reverse transcription-polymerase chain reaction assay (RT-PCR) so as to visualise these transcripts in the RNA...
