[62] discovered the highest recovery rate using only the EasySepTM human CD45 depletion kit (58%) after spiking 100 SW620 colon cancer cells into 5 mL of blood, compared to the recovery rates of using only the EasySepTM EpCAM(+) FITC‐positive selection kit (25%), or a combination of both (22.5%), which were similar to our 18% recovery rate with the H1975 cell line. The gene discussed is PTPRC; the disease is colonic neoplasm.
