A method of using fish ovarian fluid for culture and preservation of mammalian cells includes obtaining ovarian fluid from a fish, and culturing mammalian cells in media including a commercially defined medium and a nutrient medium, wherein the nutrient medium includes the fish ovarian fluid. The cells may initially be cultured in a commercial medium and a conventional nutrient medium prior to culture in the fish ovarian fluid. Living cells may also be preserved by obtaining ovarian fluid from a fish, isolating the living cells, and adding the fish ovarian fluid to the living cells.

The present invention is a fibrin sealant and a method for producing a fibrin sealant from fish blood. Whole blood is drawn from the donor fish and centifuged to separate blood cells from plasma. Prothrombin and fibrinogen are extracted from this plasma, and the prothrombin is activated to thrombin. The fibrinogen and thrombin components are then combined as needed to form the fibrin sealant.

Method of extracting fish serum and using the fish serum as a blocking reagent for solid phase immunoassays. The donor fish for the serum are taken from domesticated stocks reared under controlled conditions similar to rearing conditions for herds of domestic land animals. Control of genetics, habitat, diet, and reproductive status of the donor fish permits reproducibility of results and also provides batch-to-batch consistency in serum taken from the fish.

Fish serum as a blocking reagent

A method for culturing insect cells using fish serum. The method uses serum extracted from the blood of fish to culture insect cells for various purposes. The technique has the key advantages of consistent quality, low cross reactivity, safety from infectious agents that would endanger researchers or humans and animals receiving cell culture products as therapy and has appropriate nutrients to maintain the growth of insect cells. Fish serum is used together with designated defined medium to allow insect cells to grow and populations to be maintained. The method may also be used with lumpfish to prevent the attachment of insect cells to cultureware. Serum is derived from the blood of captive stocks of fishes raised under control conditions.

A method for culturing mammalian cells using fish serum. The method uses serum extracted from the blood of fishes to culture mammalian cells for various purposes. The technique has the key advantages of 1) freedom from mammalian infectious agents that could contaminate cell lines or endanger researchers or recipients of therapeutants derived from mammalian cell culture; 2) consistent and reproducible serum content and quality; 3) low cross-reactivity; and 4) provision of the appropriate serum nutrients to maintain the growth of mammalian cells. Fish serum is used together with designated defined media to allow mammalian cells to grow and populations of these cells to be maintained. Blood serum is derived from captive stocks of fish raised under controlled conditions such that the diet, habitat, genetics, life history, and reproductive status of the fish remains substantially consistent and reproducible.
