Abstract
The present disclosure provides a method of cell sedimentation and retention of target cells, for example circulating tumour cells, CTC, from a fluid sample onto a solid support. The method comprises placing a fluid medium comprising the target cells in a fluid chamber, the fluid chamber having an open end sealed against a surface of the solid support. The method further comprises subjecting the fluid medium to centrifugation within the fluid chamber to induce sedimentation of the target cells and promote cell adhesion to the surface of the solid support. The method further comprises, post-centrifugation, positioning a fluid absorbing element in the fluid chamber to remove fluid from the fluid chamber. The method further comprises controlling a flow rate of the fluid being absorbed by the fluid absorbing element such that the sedimented cells are not detached from the surface of the solid support.
