| 摘要 |
The invention relates to a method for determining activity of 5'-nucleotidase, in which a biological sample is incubated in a manner and under conditions known per se with a nucleotide pentose monophosphate as substrate, the liberated inorganic phosphate is converted into a colored complex by treating it with ammonium molybdate and a reducing agent, color intensity is measured by a known method, and from the measured value the activity of 5'-nucle-otidase or the amount of inorganic phosphate liberated within unit time, as a figure proportional to the activity of 5'-nucleotidase, is calculated with a known calculation and/or with the aid of a calibration curve. According to the invention 5'-AMP, 5'-CMP, 5'-UMP, 5'-GMP, 5'-IMP and 5'-TMP are used as nucleotide pentose monophosphates, and measurement is performed on all of these six substrates. The invention also relates to a reagent kit for performing the above method. |
