Expression of ubinuclein transcripts in human adult and fetal tissues. The multiple tissue cDNA panels I and II (first two panels), and human fetal panel (last panel) were used as PCR templates. PCR primers specific for exon 1A–exon 2, exon 1B–exon 2, and exon 2 of ubinuclein, and for G3PDH as an internal standard, were used. cDNAs were derived from polyA⁺ RNA isolated from tissues indicated on the top and the quantity was normalized against the transcripts of several housekeeping genes. In most tissues, transcripts with exon 1A–exon 2-specific primers were detected at the equal level, whereas a transcript containing exon 1B was less abundant.
