    • A reagent for measuring a lipase activity comprised of a higher fatty acid ester having the general formula ##STR1## wherein R.sup.1 is a straight chain alkyl group; R.sup.2 is hydrogen or a halogen atom; R.sup.3 and R.sup.4 are independently a nitro group, an alkylsulfonyl group, a substituted alkylsulfonyl group or a trifluoromethyl group; G is an --SO.sub.3 M group or a group having at least one --SO.sub.3 M where M represents sodium or potassium, or, when R.sup.4 has a sulfonic acid group, may be a hydrogen atom; and Q is hydrogen, a halogen atom, an alkyl group, an alkoxy-substituted alkyl group, an alkoxy group, an alkoxy-substituted alkoxy group, a sulfonamido group, a sulfamoyl group, a carbonamido group, a carbamoyl group, or an alkylsulfonyl group. The reagent is capable of releasing a dye on enzymatic hydrolysis by the action of lipase. Because of the released dye has a light absorption zone within the longer wavelength region, it is not substantially disturbed by colored matter contained within blood making it possible to obtain excellent operability and reproducibility in the measurement of lipase activity within blood.
    • 一种用于测量脂肪酶活性的试剂,其由通式为“IMAGE”的高级脂肪酸酯组成,其中R1为直链烷基; R2是氢或卤素原子; R3和R4独立地是硝基,烷基磺酰基,取代的烷基磺酰基或三氟甲基; G是-SO 3 M基或具有至少一个-SO 3 M的基团,其中M表示钠或钾,或者当R 4具有磺酸基时,可以是氢原子; 并且Q是氢,卤素原子,烷基,烷氧基取代的烷基,烷氧基,烷氧基取代的烷氧基,亚磺酰氨基,氨磺酰基,碳酰氨基,氨基甲酰基或烷基磺酰基 组。 试剂能够通过脂肪酶的作用在酶水解上释放染料。 由于释放的染料在较长波长区域内具有吸光区域,所以基本上不会受到血液中含有的有色物质的干扰,从而可以获得优异的可操作性和在血液中测定脂肪酶活性的可重复性。
