DETECTION OR ISOLATION OF TARGET MOLECULES USING A MICROCHANNEL APPARATUS |
摘要 |
A microflow apparatus for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts. The posts are spaced across the width of a collection region in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, have arcuate cross-sections, and are randomly arranged so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic coating, preferably a hydrogel containing isocyanate moieties or a PEG or polyglycine of substantial length, and are highly effective in capturing cells or other targeted biomolecules as a result of such streamlined flow disruption. |
