首先是基因阵列 ,其次是蛋白质阵列 ,现在又有了糖芯片。美国Columbia大学基因中心最近开发了一种糖基微阵列 ,可以用来研究糖媒介的分子识别和抗感染响应。阵列是通过把糖抗原体转移到覆盖在玻璃表面的硝化纤维上来生成的 ,原来用于制造DNA斑点的自动化设备也可以完成这个工作 The first is a gene array, followed by a protein array, and now there is a sugar chip. The Columbia University Gene Center recently developed a glycan microarray that can be used to study the molecular recognition and anti-infective response of sugar media. The array is created by transferring the carbohydrate antigen onto nitrocellulose over the glass surface, and the automation that was originally used to make DNA spots can do the job
