The transgene, pFV4CAT, containing CAT reporter gene regulated by carp β actin piomoter, was expressed in independent transgenic mud loach germ lines, determined by reverse transcriptase-PCR (RT-PCR) and enzyme-linked immunosorbant assay (ELISA). Expression of the transmitted transgene was found to be tissue-specific in F1 and F2 generations. Tissue specificity of the expression was dependent on each transgenic line with reproducible patterns Liver and spleen did express the transgene more frequently than other tissues tested, and muscle and heart revealed the higher amount of CAT than other tissues, while testes showed the lowest expression level. The highest level of CAT expression in muscle from a transgenic F1 line was corresponding to 68-fold compared to the basal levels of controls.
