评价疫苗有效性的金标准T细胞和B细胞ELISPOT技术
事实:能使人生病的细菌、病毒等病原体几乎无处不在,我们的身体无时无刻不处在病原体的包围之中,但是通常情况下,我们并没有感到不适。这是因为我们有着强大的免疫系统。 人体的免疫系统是一个复杂又神奇的存在,既能帮助人体有效抵御病原体的侵害,又能维持平衡不攻击正常的人体细胞,人体免疫包括非特异性免疫和特异
干扰素释放试验(IGRAs)两种技术原理的比对
目前,临床上应用的结核感染T细胞免疫检测的IGRAs技术有两种:一是ELISPOT;一是酶联免疫吸附试验(enzyme-linked immunosorbent assay,ELISA)。IGRA-ELISPOT方法(也称为细胞检测)采用的ELISPOT技术是细胞培养技术与ELISA技术结合产生的新
ELISPOT技术原理及实验方法介绍
ELISPOT技术原理 随着酶联免疫分析技术在医学及生物学领域的广泛应用,使体外检测各种细胞因子及抗体研究有了新的突破。在研究免疫应答机制时以往常用酶联免疫吸附法(ELISA)检测体液中游离的细胞因子(CK)或抗体,但由于游离的循环抗体或CK的半哀期不同,使之在体液中不断的被代谢或与靶器官结合
