A New Filter for Isolation of Circulating Tumor Cells by Only Blood Filtration

The method described in the study focuses on the isolation of circulating tumor cells (CTCs) from peripheral blood samples using the soft micro pore filter (S-MPF), featuring a high pore density and uniform pore size, allowing for efficient separation of rare cells, such as CTCs, while minimizing cell damage. The process involves setting up a filtration apparatus with the S-MPF, passing the blood through the filter under controlled pressure, and then retrieving the captured cells for microscopic examination.
