Northern blot analysis of XAB1 mRNA in different tissues. Human multiple tissue northern blots (Clontech) were probed with a 0.54 kb fragment of XAB1 cDNA. Each lane contained 2 µg of poly(A)⁺ RNA from each tissue: spleen (lane 1), thymus (lane 2), prostate (lane 3), testis (lane 4), ovary (lane 5), small intestine (lane 6), colon (lane 7), leukocyte (lane 8), heart (lane 9), brain (lane 10), placenta (lane 11), lung (lane 12), liver (lane 13), skeletal muscle (lane 14), kidney (lane 15) and pancreas (lane 16). The β-actin cDNA was used to probe the same blot as a control. The mobility of RNA size standards is shown on the left of the blots.
