method for quantitative detection of vital ephithelialer tumour cells in body fluids

摘要

Quantitative determination (M1) of live epithelial tumor cells (A) in a body fluid by laser-scanning cytometry, is new. (M1) comprises labeling (A) in a predetermined amount of body fluid by adding: (i) anti-human epithelial antibody (Ab) coupled to magnetic beads; and (ii) same antibody coupled to a fluorophore. (A) are then concentrated magnetically, the resulting suspension immobilized on a carrier by spontaneous adhesion and (A) determined by laser-scanning cytometry. The number of (A) relative to the amount of body fluid sample is calculated.
