  • Publication number: 20220364070
    Abstract: It is necessary to establish a purification method effective for the removal of endotoxin, in order to obtain thermolysin containing a reduced amount of contaminant endotoxin. On the premise of the establishment, accurate measurement of the amount of endotoxin that contaminates thermolysin is required. The present invention addresses the problem of providing a novel measurement method which enables accurate measurement of the amount of endotoxin that contaminates thermolysin. The present invention also addresses the problem of providing thermolysin containing a reduced amount of contaminant thermolysin, and the use thereof. There is provided thermolysin containing contaminant endotoxin in an amount of 1 EU/mg or less. There is also provided a method for measuring endotoxin that contaminates thermolysin, the method including pretreatment of deactivating the thermolysin.

  • Publication number: 20140219982
    Abstract: The present invention is intended to provide a means for efficiently degrades exogenous opioid peptides. Provided is an exogenous opioid peptide-degrading enzyme preparation which contains one or more components selected from the group consisting of enzyme preparations from Penicillium citrinum, Aspergillus oryzae, and Aspergilius melleus, and exhibits a degradation activity for a wheat gluten-derived opioid peptide and a casein-derived opioid peptide.

  • Publication number: 20110200574
    Abstract: The present technology relates to an enzyme composition. The enzyme composition may be used to treat gluten intolerant subjects, including suffering from non-Celiac gluten intolerance and/or non-Celiac gluten sensitivity. The enzyme composition may also be used to reduce gluten exposure in certain individuals. For example, the enzyme composition may also be used as a prophylactic to reduce exposure to gluten oligopeptides.
