Popis: Reporter genes are increasingly being used in order to assess new approaches to immunisation with nucleic acids. In the present work goldfish (Carassius auratusL.) received theEscherichia coliβ-galactosidase (β-gal) reporter gene under control of the immediate early promoter/enhancer of the human cytomegalovirus by intramuscular injection just anterior to the dorsal fin. β-gal activity was detected at the site of injection after 4 days. Antibody to β-gal was present in the sera of fish killed at 4 and 8 weeks after DNA injection. In parallel experiments with mice only half the mice were positive for antibody, this being mainly of the IgG2a isotype, at 4 weeks after injection of DNA into their anterior tibial muscles. This suggests goldfish can sero-convert more readily than mice within 4 weeks of DNA injection using the β-gal reporter gene.
