Protein Detection with ELISA

Description

ELISA is a protein detection test that uses antibodies and a color change to identify a target in a sample. ELISA stands for enzyme-linked immunosorbent assay. It is called an immunoassay because antibodies do the detecting.

The test is carried out in a microtiter plate with small wells. In many ...

酶联免疫吸附检测(ELISA),是一种被广泛用来判断特定靶蛋白是否存在的方法。

偶联了酶的抗体,经过一系列的孵育,洗脱步骤,将识别包被在96孔板底部的靶蛋白。当加入底物到样品中后,会发生酶促反应造成颜色变化,这使得可以鉴别并定量靶蛋白。

在讨论如何进行ELISA之前,让我们先熟悉一下将要用到的设备和试剂。

ELISA反应通常在96孔平底板中进行。平的底部会有助于实验样品,捕捉抗体和检测抗体的均匀分布 。

ELISA可检测靶蛋白是否存在于实验的溶液中。尿液,细胞培养液,血清,这些都是常见的实验样品。

ELISA实验中,直接与靶...
