Devices and methods for isolating target cells |
摘要 |
A cell isolating device and method is provided to concentrate or isolate cells with specific characteristics from a mixture of different cell types. One embodiment may comprise two subtypes of antibodies that are directly conjugated to biotin (Abb) and conjugated to a fluorescent molecule (Abf). The conjugated antibodies (Abb+Abf) bind to the target cells in a mixed cell suspension. The cell suspension is then passed over an immobilized avidin or streptavidin substrate on a glass microscope slide. The biotinylated target cells adhere to the avidin/streptavidin substrate, while the unbound cells are washed off and collected in a wicking member. Captured cells on the avidin/streptavidin substrate may then be visualized directly using a fluorescent microscope or detected and enumerated via an on-board fluorescent detection device.
