Fig. 7. Expression of GAR17 and GAR22 mRNAs in mammalian tissues. (A) Northern blot analysis of GAR17 expression in human tissues. A human multiple-tissue northern blot was hybridized with a hGAR17-specific probe. As mRNAs of hGAR17 and hGAR17ß differ from each other by only 47 bp, they cannot be distinguished on a northern blot. (B) Northern blot analysis of GAR22 expression in human tissues. A human multiple-tissue northern blot was hybridized with a hGAR22-specific probe. hGAR22 and ß transcripts are indicated with arrows. (C) Northern blot analysis of GAR22 expression in mouse tissues. A mouse multiple-tissue northern blot was hybridized with a mGAR22-specific probe. mGAR22 and ß transcripts are indicated with arrows. The sizes of molecular mass markers are in kb.
