Fig. 7. Tissue-specific expression of hRUL138-related mRNAs. A multiple tissue Northern blot containing poly-A⁺ RNA from the indicated human tissues was probed with a ³²P-labeled hRUL138 DNA (nt positions 1497-1998 of the hRUL ORF) and analyzed by phosphorimaging. For control, the same blot was reprobed with an actin probe (lower panel). Numbers on the left show the positions of RNA size markers (in kb); the major hRUL transcripts are indicated by the arrowheads on the right.
