  • Publication number: 20230123857
    Abstract: A process of using a fish plasma component in a nutrient medium for cell culture includes obtaining a fish that is a progeny of domesticated broodstock that are reared under consistent and reproducible conditions. Blood is obtained from the fish, and plasma is separated from the blood. One or more specific components of the plasma are then extracted, and cells are cultured in a nutrient medium using the one or more extracted plasma components, and none of any remainder of the plasma. The plasma and/or the plasma components is/are tested for presence and/or level of endotoxin. Extracting the one or more specific components of the plasma, and/or culturing the cells is only performed if the testing indicates an endotoxin level below a predetermined threshold. The cells cultured using the extracted one or more plasma components are other than fish cells.

  • Publication number: 20210290123
    Abstract: A method for obtaining large volumes of blood from farmed fish especially farmed salmon includes providing a container to which a negative internal pressure is applied. Input tubes to the container include valves to control the flow of fluid into the container through the input tubes. Needles at the distal ends of the tubes are used to access blood vessels of a fish. On opening of the valve associated with the tube connected to the needle accessing the fish blood vessel, the negative pressure in the container draws blood from the fish into the container. Multiple input tubes can be used to access the blood vessels of a corresponding number of fish at the same time to rapidly collect blood from an entire harvest of fish. The method preserves valuable plasma proteins, and prevents contamination of the blood.

  • Publication number: 20140346073
    Abstract: A wound dressing includes a backing material, and thrombin, applied to the backing material. Preferably, the backing material includes biodegradable polyester, such as electrospun polycaprolactone. The thrombin preferably includes salmon thrombin adsorbed onto the backing material. A process of fabricating a wound dressing includes applying thrombin to the backing material. Preferably, the thrombin is prepared from the plasma of a salmonid. The thrombin is applied to the backing material by adsorbing the thrombin onto the backing material, preferably after applying a detergent solution to the backing material. The dressing can be lyophilized and vacuum-sealed within an air-tight wrapping.

  • Publication number: 20090124548
    Abstract: A method includes applying salmon fibrin at a central nervous system injury site. For example, applying salmon fibrin can include injecting salmon fibrin. The method can also include causing the suppression of astrocyte activation, whereby glial scarring is at least reduced. The functional recovery of a patient who has suffered a central nervous system injury is promoted according to this method.

  • Publication number: 20060155235
    Abstract: A hemostatic compression bandage includes a flexible backing element, a powdered hemostatic substance, and a flexible film element. The backing element includes a first containment region. The film element includes a second containment region corresponding to the first containment region. The film element is removably attached to the backing element so as to contain the hemostatic substance between the backing element and the film element within a volume defined by the first containment region and the second containment region. The backing element includes a pressure region located outside of the first containment region. The film element includes a pull-tab region located outside of the second containment region and at a first side of the bandage. The pull-tab region has sufficient length to be folded back across the second containment region and extending beyond a second side of the bandage that is opposite the first side of the bandage.

  • Patent number: 6986318
    Abstract: A sail assembly includes a sail, a mast, a coupler, and a fastener. The mast is attached to a first side of the sail. The coupler is attached to the mast and is used to couple the mast to a handle portion of a paddle. The fastener is attached to the sail at a location opposite the first side of the sail and is used to fasten the sail to the blade portion of the paddle. The sail is held in an open position when the mast is coupled to the handle portion of the paddle at a right angle to the paddle and the sail is fastened to the blade portion of the paddle. Thus, when the mast is supported upright and the end of the sail is connected to the paddle, the sail is open and usable to propel the boat under power of the wind.

  • Patent number: 6007811
    Abstract: 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.

  • Patent number: 5602041
    Abstract: 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.

  • Patent number: 5498540
    Abstract: 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.

  • Patent number: 5443984
    Abstract: 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.
