ELISpot实验操作流程
ELISPOT全名为酶联免疫斑点检测，英文：Enzyme-linked Immunospot Assay。它结合了细胞培养技术与酶联免疫吸附技术（即ELISA技术），能够在单细胞水平检测细胞因子的分泌情况。其技术原理，一句话概括就是：用抗体捕获培养中的细胞分泌的细胞因子，并以酶联斑点显色的方式将其表
ELISPOT（酶联免疫斑点法）技术
酶联免疫斑点技术(Enzyme Linked Immunospot Assay, ELISPOT)是细胞免疫学研究中最敏感的检测方法之一，可以在单细胞水平对抗体分泌细胞(ASC)及细胞因子(CK) 分泌细胞进行检测。由于是单细胞水平检测，ELISPOT比ELISA 和有限稀释法等具有更高的灵敏性，能
