    • 摘要: OBJECTIVE To establish a reversed phase ion-pair HPLC method for the determination of the activity of nucleo-side diphosphate kinase (NDPK) in human red blood cells (RBC). METHODS RBC with reaction substrates (dADP and dGTP) and other reaction mixtures were incubated at 37 °C for 5 min.then inactivated by heating at 100 °C for 10 min.and cen-trituged with supernatant sample for analysis. dATP concentrations were quantified for the determination of the activity of NDPK in human RBC. Separation was achieved by SymmetryShield TM RP18(150 mm×3. 9 mm, 5 μm) with UV detection at 260 nm and column temperature of 25 t. Using gradient elution,the mobile phase A consisted of mixture of 20 tnmol·'L-1 KH2PO4--K2HPO4buffer solution and ion-pairing reagent 5 mmol·L-1TBAHS,and mobile phase B was acetonitrile. RESULTS NDPK could catalyze ADP + dGTP←→dATP + dGDP reaction specifically. The calibration curve was linear over the range of 4. 33 -43. 34 μmol·L-1 (r2 - 1.000) and the limit of quantitation was 4. 33 μmol·L-1. The intra- and inter-assay coefficients of variation were less than 5. 53% and 6. 69% , respectively. The mean analytical recoveries of dATP were 98. 4% - 104. 2% and the mean absolute recoveries were all more than 83%. A stability study showed that dATP samples in RBC were stable at room temperature or at 4 t for at least 24 hours,as well as for at least 30 days at - 80 °C after three freeze-thaw cycles. CONCLUSION This method is -simple,rapid,sensitive,specific,and can be applied to study the relationship between activity of NDPK and efficacy and toxicity of thiopurines.%目的:建立测定人体红细胞(RBC)内核苷二磷酸激酶( NDPK)活性的反相离子对高效液相色谱法.方法:稀释RBC中加入反应底物(dADP和dGTP)及其他反应混合液后,37°C孵育5 min,100°C灭活10 min,离心取上清液进样分析.以反应产物dATP定量分析NDPK活性.色谱柱为SymmetryShield TM RP18(150 mm×3.9mm,5μm),检测波长为260 nm,柱温为25°C;采用梯度洗脱,流动相A为20 mmol·L-1 KH2 PO4-K2 HPO4缓冲液、加入离子对试剂5mmol· L-1四丁基硫酸氢铵(TBAHS)溶液,流动相B为乙腈.结果:NDPK催化反应dADP+ dGTP←→dATP+ dGDP反应特异性良好,RBC内dATP的线性范围为4.33~43.34 μmol·L-1(r2=1.000),定量下限为4.33 μmol·L-1.日内及日间RSD分别小于5.53%和6.69%,准确度为98.4%~104.2%,平均绝对回收率大于83%;dATP样品在室温或4°C、- 80°C保存30d及反复冻融3次稳定性良好.结论:该法操作简便快速、灵敏、专属性强,可应用于人体RBC内NDPK活性测定,为研究NDPK活性与嘌呤类药物反应相关性提供基础.
