Intended use
This immunoassay kit allows for the in vitro quantitative determination of human Beta-amyloid protein 42 concentrations in serum, Plasma, tissue homogenates and Cell culture supernates and Other biological fluids.
Test principle
The microtiter plate provided in this kit has been pre-coated with an antibody specific to Beta-amyloid protein 42. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for Beta-amyloid protein 42 and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain Beta-amyloid protein 42, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Beta-amyloid protein 42 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

【原创】Protein A Sepharose 之进化篇。。。
[img][/img]Protein A 柱之进化 Protein A是一种金黄色葡萄球菌细胞壁蛋白质，能特异性地与人和哺乳动物抗体（主要是IgG）的Fc区结合。因而，将Protein A 与琼脂糖凝胶以一定的方式结合，可制备用于抗体纯化的亲和填料。 早期的Protein A柱结合的都是天然Protein A。天然Protein A由5个IgG结合域和其它未知功能的非Fc结合域组成，分子量约42KD，结构如图1所示。这种柱子对IgG的亲和能力很强，可以吸附大量的lgG。但同时，天然
