The Agilent spectral flow cytometer plays a crucial role in vaccine research. At Yunnan University, professor Zhang Zijie's multidisciplinary research team adopts a multi-omics approach. They delve into the systemic impact of genetic variations and environmental interactions on gene expression regulation and how these factors influence vaccine immune responses and disease occurrence. The Agilent NovoCyte Opteon spectral flow cytometer is indispensable in the process.
