RNA expression analysis with RT-PCR. (A) RT-PCR analysis of ZNF127, IPW, PAR-5, and PAR-1. The amplification was present in RT+ reactions (lane 4), but not in RT− reactions (lane 3). Lane 1, normal human brain mRNA for positive control; Lane 2, DNA derived from the translocation patient serving as positive control. It was omitted for IPW since RT-PCR spanned an intron. Lane 3, RNA derived from fibroblasts of the patient was incubated without reverse-transcriptase as control (RT−); Lane 4, RNA derived from the patient was incubated with reverse-transcriptase (RT+). (B) RT-PCR analysis for SNRPN exons proximal and distal to the translocation breakpoint. The amplification was present in RT+ reactions (lane 3), but not in RT− reactions (lane 2). Lane 1, RT-PCR product from mRNA derived from a normal human brain; Lane 2, RT-PCR product from RNA derived from the patient’s fibroblast culture without reverse-transcriptase (RT−); Lane 3, reaction product from RNA derived from the patient’s fibroblast culture with reverse-transcriptase (RT+).
