Figure 1From: Local IGFBP-3 mRNA expression, apoptosis and risk of colorectal adenomas RT-PCR demonstrates human 195-nucleotide (nt) IGFBP-3 products using cDNA transcribed from human colonic biopsy RNA. cDNA samples were prepared as described in Methods. GAPDH control (358 nt) is shown below for human samples. Controls at left are PCR products using IGFBP-3 standard (+ Control) and 'no reverse transcriptase (RT)' (-Control) cDNAs.Back to article page
