Immunohistochemistry of FGF-1 staining in crysections of Bovine oviduct. The sections were treated with 0.5% H2O2 in PBS to reduce endogenous peroxidase activity. (A) The section was incubated with AP02008SU (1/5000). Positive staining appears red, the nuclei are stained blue. Scale bar = 12.6 µm. (C) Control section incubated with Rabbit IgG. Scale bar = 20 µm. Gabler C et al. J Reprod Fertil. 1997 Mar;109 (2):213-21.
