体外展示技术,最好的例子是噬菌体和酵母展示,在大约20年前首次描述用于选择抗体。从那时起,已经选择了大量的抗体,其中一些具有显著的特性,并在使用这些方法时进行了改进。第一批使用体外展示方法获得的抗体现在已经进入临床,还有更多的抗体正在等待。在这里,我们讨论了该技术的范围,一些强大的抗体选择,以及在后基因组世界的未来潜力。体外展示技术提供的独特优势包括仔细定义选择条件的能力,允许衍生识别预定义表位或构象的抗体,进一步改进所选抗体,高通量应用的潜力和编码所选抗体的基因的立即可用性。我们预计,这些技术的高通量潜力将很快导致其用于选择针对所有人类蛋白质的抗体。
In vitro display technologies, best exemplified by phage and yeast display, were first described for the selection of antibodies some twenty years ago. Since that time a large number of antibodies, some with remarkable properties, have been selected and improved upon using these methods. The first antibodies derived using in vitro display methods are now in the clinic, with many more waiting in the wings. Here we discuss the scope of the technology, some of the powerful antibodies selected, and the future potential in a post-genomic world. Unique advantages offered by in vitro display technologies include the ability to carefully define selection conditions, allowing the derivation of antibodies recognizing predefined epitopes or conformations, the further improvement of selected antibodies, the potential for high throughput applications and the immediate availability of genes encoding the selected antibody. We anticipate that the high throughput potential of these technologies will soon lead to their use to select antibodies against all human proteins.
