Figure 3: Immunohistochemical localization of basigin, MCT1 and MCT2 in mouse testes. Testes from adult mice were immunostained with anti-basigin ( a and b ), anti-MCT1 ( d and e ) or anti-MCT2 ( g and h ) antibody. Roman numerals indicate the stage of the seminiferous epithelium. ( c , f , i) negative controls lacking primary antibodies, anti-basigin ( c ), anti-MCT1 ( f ) and anti-MCT2 ( i ). Scale bars: 100 μm.
