In collaboration with Dr Magnus Breitholtz and Ulrika Dahl at the Department of Applied Environmental Science at Stockholm University, an assay for determination of ecdysteroid levels in C. finmarchicus have been established. Recently, we published a paper together where ecdysteroids along with several CYP-enzymes were analyzed in C. finmarchicus at different developmental stages:
Hansen, Bjørn Henrik; Altin, Dag; Hessen, Kristine Mordal; Dahl, Ulrika; Breitholtz, Magnus; Nordtug, Trond; Olsen, Anders J. 2008. Expression of ecdysteroids and cytochrome P450 enzymes involved in lipid turnover and reprodustion in Calanus finmarchicus (Crustacea: Copepoda). General and Comparative Endocrinology, 158, 115-121.
