使用磁悬浮定量细胞密度和抗原特性

Executive Industry Relevance

Magnetic levitation enables rapid, label-free separation of cells based on intrinsic density, supporting early discovery workflows where target validation and phenotypic screening require minimal manipulation. The method provides quantitative readouts of antigen presence through bead-bead complex formation, offering a scalable approach for assay development in hematology-focused discovery programs. Its compatibility with standard imaging reduces dependency on specialized instrumentation, enhancing accessibility for cross-functional R&D teams.
