An homologous radioimmunoassay for coho salmon (Oncorhynchus kisutch) vitellogenin, with general applicability to other Pacific salmonids.
This paper describes an homologous radioimmunoassay for coho salmon vitellogenin that demonstrates parallel cross-reactivity for plasma vitellogenin of all Pacific salmonids tested (chinook, chum, coho, pink, and sockeye salmon, and cutthroat and rainbow trout), but not for Atlantic salmon or two nonsalmonids: common carp and sablefish. Plasma vitellogenin levels were high in ovulatory female Pacific salmonids (micrograms/ml to mg/ml range), but were mostly nondetectable in spermiating males of the same species.
