  Provided is a method of producing a nucleator masterbatch, by which a nucleator masterbatch capable of improving the transparency and the physical properties of an olefin resin can be produced. This method is a method of producing a masterbatch in which a nucleator is blended in an olefin polymer, the method being characterized by comprising the step of polymerizing an olefin monomer with incorporation of a nucleator component, which is dissolved in an organoaluminum compound or in an organoaluminum compound and an organic solvent, before or during polymerization of the olefin monomer such that the nucleator component is blended in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the olefin polymer obtained by the polymerization of the olefin monomer.

  A method is provided for determining the activity of an enzyme which releases methylumbelliferone (MU) from an MU-containing substrate wherein the enzyme has a pH optimum below the pKa of MU comprising: contacting a sample suspected of containing the enzyme with the MU-containing substrate at a pH suitable for activity of the enzyme to allow release of MU by the enzyme; contacting the sample with light of a wavelength in the range of about 310 nm to about 350 nm; determining fluorescence produced by the released MU, thereby determining the activity of the enzyme. This real time method provides improved diagnostic methods, for example for diseases associated with an abnormal level of activity of a glycosidase. The real time assay also can be used to screen compounds for their ability to modulate enzyme activity using MU-containing substrates.

  提供了一种确定酶活性的方法，该酶可从含 MU 的底物中释放甲基伞形酮（MU），其中酶的 pH 最适值低于 MU 的 pKa，该方法包括在适合酶活性的 pH 值下，将疑似含有酶的样品与含 MU 的底物接触，使酶释放 MU；将样品与波长在约 310 nm 至约 350 nm 范围内的光接触；确定释放的 MU 产生的荧光，从而确定酶的活性。这种实时方法提供了改进的诊断方法，例如用于诊断与糖苷酶活性水平异常有关的疾病。这种实时检测法还可用于筛选化合物，以确定它们利用含 MU 底物调节酶活性的能力。
