Wie hoch ist die spezifische (Enzym)aktivität? d.h. wie viel Gramm Enzym sind in einem Aliquot verkauftem Enzym (bzw. wie viel nicht-Enzym Beimengen sind darin enthalten) -> ich benötige das für die Enzymmengenangaben in einem Patentantrag!
1 answer-
The minimum activity specification for this product is 0.5 µ/mg. This value varies from lot to lot. A review of several recent lots reveals a general range of 0.5 µ/mg – 1.1 µ/mg,
A 1-gram vial with an activity of 0.5 U/mg would contain 500 units. The same lot in the 10-gram vial would contain 5000 units.
The purity of this product is not tested. The presence or absence of any other non-enzyme admixtures has not been determined and such values are unavailable.A lot-specific or sample Certificate can be accessed in the DOCUMENTATION section of the Product Detail Page under 'Certificate of Analysis':
