Immunological cross-reaction between pituitary gonadotropin from North Atlantic fish
Pituitary extracts of 14 species of fish from the North Atlantic were tested in rainbow trout and carp gonadotropin radioimmunoassays (RIA). The poor cross-reaction and low gonadotropin content measured in the pituitary extracts indicate that RIA used for trout and carp gonadotropins are unsuitable...
