  • Patent number: 5317084
    Abstract: Lactoferricin (Trade Mark), also called LFCIN (Trade Mark), a potent antimicrobial peptide, is produced by contacting an enzymatic hydrolysate of bovine lactoferrin or any mixture of peptides containing lactoferricin preferably with a butyl moiety-containing hydrophobic interaction chromatography medium, or alternatively with a carboxymethyl moiety-containing cation-exchange chromatography medium, rinsing the medium to remove unbound peptides, desorbing the lactoferricin solution at constant pH, and desalting the desorbed solution. The utility of the process is illustrated, for example, as follows. An enzymatic hydrolysate of bovine lactoferrin (600 g) was contacted with 3000 ml of BUTYL-TOYOPEARL 650M, the medium was rinsed with water, and then with McIlvaine (citric acid-sodium phosphate) buffer at pH 7.0., and lactoferricin was desorbed with McIlvaine buffer at pH 5.0.

  • Patent number: 5290918
    Abstract: The present invention relates to a process of making a concentrate of coagulation proteins starting with whole human or animal plasma. This concentrate is used as a biological adhesive when extemporaneously mixed to thrombin. The concentrated proteins include mostly fibrinogen, fibrin stabilizing factor (factor XIII) and fibronectin. The claimed process has the advantage of being short of execution while providing an excellent yield of coagulable proteins. No protease inhibitor has to be added during the process. The process involves steps of acidic precipitation in presence of amino-6 hexanoic acid which prevents co-precipitation of plasminogen with the desired coagulable proteins. The proteins so obtained are very stable after reconstitution in water for at least 24 hours at room or body temperature. After mixing with thrombin, the adhesive shows excellent strength and biocompatibility.
