Dual-Color ELISPOT Assay for the Simultaneous Detection of IL-2 and/or IFN- Secreting T CellsINTRODUCTIONThe enzyme-linked immunospot (ELISPOT) assay measures the secretion intensity of effector molecules released by immune cells inresponse to ex vivo antigenic stimulation, as well as the frequency of these responding cells. This assay is highly sensitive, quantitative, easy to use, and amenable to hig......阅读全文

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
ELISPOT与ELISA的区别
1.ELISA通过显色反应，在酶标仪上测定吸光度，与标准曲线比较得出可溶性蛋白总量。2.ELISPOT通过显色反应，在细胞分泌这种可溶性蛋白的相应位置上显现清晰可辨的斑点，可直接在显微镜下或通过仪器对斑点进行计数，1个斑点代表1个细胞，从而计算出分泌该蛋白的细胞的频率。3.由于是单细胞水平检测，EL
