Olink® Explore for High-Throughput Protein Biomarker Discovery in Cerebrospinal Fluid
摘要
The Olink® Explore platform enables high-throughput protein biomarker discovery through Proximity Extension Assay (PEA) technology combined with Next Generation Sequencing (NGS) on Illumina instruments. This approach allows for the simultaneous measurement of thousands of human plasma proteins with minimal sample volumes. The Explore 3072 library offers approximately 3000 protein assays, while the smaller Explore 384-plex panels cater to more targeted studies. The platform excels in detecting low-abundance proteins, such as cytokinesCytokines and chemokines, and is particularly effective for challenging sample types like cerebrospinal fluid (CSF)Cerebrospinal fluid (CSF), where protein content is typically low. In this chapter, we emphasize critical dry-lab considerations, including CSFCerebrospinal fluid (CSF) handling, study design, sample size determination, instrumentation requirements, and post-experiment data management. Proper planning and execution of these factors are essential for optimizing performance and ensuring reliable outcomes when using Olink®'s platform.
