Relative quantitation of human TFPI-2 transcripts in various normal and tumor cells. Agarose gel electrophoresis analysis of RT-PCR products from various cells and tissues. Panel A depicts TFPI-2 (622 bp) and asTFPI-2 (289 bp) transcripts, while panel B depicts cyclophilin A transcripts. The data presented in panel C represents the amount of transcripts normalized to 10,000 arbitrary units of cyclophilin A amplified from each sample. Each column represents the average of two amplification reactions (error bars represent standard deviation) performed on a single cDNA sample reverse-transcribed from RNA derived from each sample.
