Fig. 3 The specificity of polyclonal (left) and monoclonal (right) anti-TH antibodies for TH1 and TH2 proteins was tested on Western blots. Lanes 1 and 2 correspond to proteins extracted from mouse (Ms) and zebrafish (ZF) brains. Lanes 3 and 6 correspond to zebrafish TH1, and lanes 4 and 7 correspond to TH2, both expressed in COS7 cells. The band of the TH2 shows a lower molecular weight than TH1, and it is labeled much weaker than TH1 by the two antibodies. Lanes 5 and 8 correspond to negative controls (CNT), with lane 5 from untransfected COS7 cells, and lane 8 from COS7 cells transfected with a plasmid in which TH2 is inserted in a reverse orientation. The blot has been overexposed, in order to see the TH2 band better.
