  • Publication number: 20230052545
    Abstract: Described are compositions, in particular lyophilizates, containing proteolytic enzymes, and methods for producing the compositions. Typically these compositions contain one or more proteases with collagenase activity and a neutral protease, for example, thermolysin. The compositions are free of acetate salts. Surprisingly, such compositions can be dissolved in water more rapidly than lyophilized protease mixtures of the state of the art.

  • Patent number: 9574186
    Abstract: The present invention deals with the proteolytic enzyme thermolysin which tends to be unstable in aqueous solution. The invention provides methods and compositions to enhance the stability of dissolved thermolysin in aqueous solution. Thermolysin, crude thermolysin or a lyophilisate containing thermolysin and one or more salts, is contacted with an aqueous buffer with a low salt concentration and a first solution is formed. Subsequently, a further salt in solid form is added and dissociated, thereby forming a second solution comprising thermolysin in a stabilized form.

  • Patent number: 7956167
    Abstract: The present invention provides a method for purifying Clostridium histolyticum collagenase type I and type II proteins from a complex mixture by subsequently performing a precipitation with ammonium sulfate, hydrophobic interaction chromatography, cation exchange chromatography, and anion chromatography. Conditions are provided which lead to a stabilized, partially purified preparation even after the precipitation step. The method of the invention leads to a quick and efficient removal of other proteolytic activities. The preparations according to the invention provide exceptionally pure and intact collagenase type I and type II proteins which are enzymatically active. The invention also provides blends of the two isolated proteins. The invention further provides the use of the purified collagenase proteins or blends thereof for treating a tissue sample in vitro.

  • Patent number: 7482145
    Abstract: By deglycosylating an enzyme derived from a eukaryotic organism prior to forming a conjugate, i.e. prior to attaching the enzyme to a molecule capable of binding to a target molecule, the sensitivity of an assay for detecting the presence or determining the quantity of a target molecule, in which the conjugate is used as a labelled component, can be increased. The present invention provides conjugates, methods for providing the same, use of such conjugates as well as kits containing the conjugates.
