In biological assays, systematic variability, known as a batch effect, can often confound the effects of true biological conditions and has been well documented for a variety of high-throughput technologies. In microplate-based multiplex experiments, such as Luminex or OLINK assays, researchers need to consider both position and plate effects. Those effects can be easily accounted for if the experiments are properly designed, which includes randomization of the samples across multiple experimental runs. However, doing the ad hoc randomization becomes challenging when handling multiple samples. PlateDesigner is the first web-based application that provides randomization for microplate experiments, ensuring that the main principles of the experimental design, such as grouping samples from the same biological units and balancing the distribution of experimental conditions, are applied. Creating randomizations with PlateDesigner is simple and the results can be exported in a variety of formats, and easily integrated with microplate readers and statistical analysis software.

在生物测定中,系统性变异,也称为批次效应,常常会干扰真实生物条件的影响,并且已经在各种高通量技术中得到了充分的证明。在基于微孔板的多重实验中,如 Luminex 或 OLINK 分析,研究人员需要考虑位置和板效应。如果实验设计得当,包括将样品随机分配到多个实验运行中,就可以轻松地解释这些效应。然而,当处理多个样本时,进行临时随机化就变得具有挑战性。PlateDesigner 是第一个提供微孔板实验随机化的基于网络的应用程序,确保了实验设计的主要原则,如从相同的生物学单位分组样本和平衡实验条件的分布,得到应用。使用 PlateDesigner 进行随机化非常简单,结果可以以多种格式导出,并与微孔板阅读器和统计分析软件轻松集成。
