Efficient Isolation and Accurate InSitu Analysis of Circulating Tumor Cells Using Detachable Beads and a High-Pore-Density Filter

Analysis of cancer cells: A new technique isolates rare circulating tumor cells (CTCs) and analyzes their protein expression by the use of detachable beads and high-pore-density filters. This technique shows significantly improved efficiency in the isolation of rare CTCs from peripheral blood and enables accurate measurement of insitu protein-expression levels.
