摘要:

为了检测糖基化产物——糖化蛋白的含量,探索出简便快速的测定蜂王浆中糖化蛋白的方法。采用氯化硝基四氮唑蓝(NBT)比色法,以1- 脱氧-1- 吗啉-D- 果糖(DMF)为标准物,测定蜂王浆中糖化蛋白的含量。结果表明,DMF 与NBT 反应的最佳条件为:反应温度为57℃,时间为20min,表面活性剂Triton 体积分数为0.02%,pH 值为10.8,NBT 浓度为0.5mmol/L。该方法能够简便快速地对蜂王浆中的糖化蛋白进行测定,且准确度高、灵敏度高,是一种较为实用的测定方法。

Abstract:

In order to establish a rapid and convenient method for determining the content of glycosylated protein in royal jelly, a colorimetric assay was developed using nitroblue tetrazolium (NBT) chloride and 1-deoxy-1-morpholino-D-fructose (DMF) was used as the standard substance. Results indicated that the optimal reaction conditions between DMF and NBT were 57 ℃ of reaction temperature, 20 min of reaction time, 0.02% Triton, pH 10.8, and 0.5 mmol/L NBT. This method is a convenient and rapid determination method for glycosylated protein in royal jelly with high accuracy and sensitivity.

Key words: royal jelly, glycosylated protein, colorimetric assay
