(A) Expression of AGS3 mRNA. Analysis of a rat multiple
tissue Northern blot with an AGS3 probe shows a 2.3-kb mRNA in heart
(lane 1) and a 3.5-kb mRNA in brain (lane 2). No mRNAs were detected in
spleen (lane 3), liver (lane 4), lung (lane 5), skeletal muscle (lane
6), kidney (lane 7), or testis (lane 8) under these conditions.
(B) Expression of AGS3 protein. Analysis of a rat
multiple tissue Western blot (75 μg protein/lane) with
affinity-purified AGS3 IgG (8.5 μg/ml in TBS, 0.1% Tween 20,
5% FCS) showing that AGS3 protein is widely expressed. A 75-kDa
protein is detected in brain (lane 2) and testis (lane 6). Liver (lane
1), kidney (lane 4), heart (lane 8), and pancreas (lane 9) showed a
single protein band at 53, 42, 26, and 35 kDa, respectively. No AGS3
immunoreactivity was detected in lung (lane 3), spleen (lane 5), and
ovary (lane 7) under these conditions.
