CaptureELISA
实验概要Capture ELISA (also known as "sandwich" ELISA) is a sensitive assay to quantitate picogram to microgram quantities of substances (such as hormones, cell signaling chemicals, infectious disease antigens and cytokines.). This type of ELISA design may be needed rather than a direct or indirect ELISA for several reasons. The substance to be analyzed may be too dilute to b......阅读全文

电子捕获检测器(electron－capture－detector,ECD)结构
检测室内有正负电极与β-射线源，目前所使用的最佳的放射源是Ni63，在衰变中没有γ辐射，产生的β射线能量低，半衰期长，可用到400℃。
电子捕获检测器(electron－capture－detector,ECD)原理
检测室内的放射源放出β-射线粒子(初级电子)，与通过检测室的载气碰撞产生次级电子和正离子，在电场作用下，分别向与自己极性相反的电极运动，形成检测室本底电流，当具有负电性的组分(即能捕获电子的组分)进入检测室后，捕获了检测室内的电子，变成带负电荷的离子，由于电子被组分捕获，使得检测室本底电流减少，

解决非特异吸附的新方法
免疫分析中，非特异的蛋白吸附常常是阻碍高灵敏度的一个重要的因素。来自中科院等单位的研究小组开发了一种新的固相载体，有望达到"0"非特异吸附。以下是他们在 Analytical Chemistry 的文章摘要。Integrated Poly(dimethysiloxane) with an Intri

ELISA实验
酶联免疫吸附实验（ELISA）可以用于：（1）检测大分子抗原和特异性抗体等；（2）具有快速、灵敏、简便、载体易于标准化等优点。实验方法原理ELISA的基础是抗原或抗体的固相化及抗原或抗体的酶标记。结合在固相载体表面的抗原或抗体仍保持其免疫学活性，酶标记的抗原或抗体既保留其免疫学活性，又保留酶的活性。
