Glycan microarrays provide a high-throughput technology for rapidly profiling interactions between carbohydrates and glycan-binding proteins (GBPs). Use of glycan microarrays involves several general steps, including construction of the microarray, carrying out the assay, detection of binding events, and analysis of the results. While multiple platforms have been developed to construct microarrays, most utilize fluorescence for detection of binding events. This chapter describes methods to acquire and process microarray images, including generating GAL files, imaging of the slide, aligning the grid, detecting problematic spots, and evaluating the quality of the data. The chapter focuses on processing our neoglycoprotein microarrays, but many of the lessons we have learned are applicable to other array formats.
聚糖微阵列提供了一种高通量技术,用于快速分析碳水化合物与聚糖结合蛋白(GBP)之间的相互作用。使用聚糖微阵列涉及几个一般步骤,包括微阵列的构建、进行检测、结合事件的检测以及结果分析。虽然已经开发了多个平台来构建微阵列,但大多数都利用荧光来检测结合事件。本章描述了获取和处理微阵列图像的方法,包括生成GAL文件、玻片成像、网格对齐、检测有问题的斑点以及评估数据质量。本章重点介绍处理我们的新糖蛋白微阵列的方法,但我们学到的许多经验教训也适用于其他阵列格式。
