Northern blot analysis of the expression of DDX10 and NUP98 genes in human tissues. Northern blot filters from human adult and fetal tissues (Clontech) were used for analysis. Probes: (A), DX-FRG116 (nucleotides 21 to 1347 of DDX10 cDNA18 ); (B), NP-FRG123 (nucleotides 93 to 2655 of NUP98 cDNA21 ); (C), β-actin. kb, kilobases.
