Fig. 2. Northern blot analysis of MACF1. Expression of MACF1 (MACF1a/b) in adult mouse tissues. A multiple tissue blot was hybridized with 32P-labelled cDNA probes that recognized the plakin domain of both MACF1a and MACF1b (NB1 in Fig. 1B) or the PRD region of MACF1b (NB2 in Fig. 1B). Ethidium bromide stained 28S ribosomal RNAs were used as the loading control.
