摘要: 悬液芯片系统诞生于20世纪90年代中期,由美国Luminex公司的研制。该系统使用荧光编码的聚苯乙烯微球作为特异性反应的固相载体,通过偶联试剂的作用,将蛋白质、寡核苷酸、小分子肽类及脂肪偶联到微球的表面构成不同的检测探针。在反应体系中,检测探针通过特异性反应(如抗原―抗体,配体―受体,核酸互补碱基对)捕获与探针相对应的分析物,用荧光标记物标记与探针结合的分析物得到悬液芯片系统的检测物。依据微球内部红色和橙色荧光染料比例的不同,将供悬液芯片系统使用的聚苯乙烯微球分为100种不同的型号。检测器对荧光标记物荧光强度进行检测的同时能分辨不同型号的微球,并将不同型号微球对应的标记物的荧光强度进行分别记录,最终实现一次分析多种检测物的目的。作者综述了悬液芯片系统的原理及在蛋白质、核酸检测领域的研究进展。

Abstract: In the mid-1990s, the Luminex Corporation(USA) exploited the first suspension array system, which used fluorescent-coded carboxylic beads as solid carrier. Proteins, oligonucleotides, small peptides and lipids have been adsorbed or chemically coupled to the surface of microspheres to format detected probe. According to the different proportion of red and orange fluorescent dyes inside beads, the beads are divided into 100 different types. The intensity of fluorescent associated with beads and fluorescent probe are tested simultaneously by special detector on suspension array system. The detector can distinguish beads of different types basing on different proportion of two fluorescent dyes while recording the intensity of fluorescent from probe on every bead to achieve high throughput detection. This article reviews the research regarding suspension assay system and its application in detection.
