  • 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: 10227642
    Abstract: The present invention relates to a formulation of a thermostable DNA polymerase which is completely free of detergents and its particular use in real time polymerase chain reaction (PCR). Such a formulation may be obtained if the selected purification method does not require the addition of a detergent at any purification step.

  • Patent number: 9663769
    Abstract: The present disclosure provide novel variants of T7 RNA polymerase. Embodiments of T7 variants, according to the instant invention, include a Cysteine-Serine substitution on position 723 of the amino acid sequence of the T7 polypeptide. Embodiments of T7 variants according to the instant invention have a DNA-dependent RNA polymerase enzymatic activity and a reduced tendency to form intramolecular homodimers by way of oxidizing thiol groups. The amino acid substitutions within the T7 variants disclosed herein impact minimally, if at all, the RNA polymerase activity of the T7 polypeptide. Further, the mutations of the disclosed embodiments may optionally be combined with mutations which provide enhanced thermostability compared to the wild-type reference.

  • 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.
