    摘要： The present invention discloses a method of monitoring haptotaxis comprising: providing a device for monitoring haptotaxis having a housing defining a chamber. The chamber includes: a first well region including at least one first well, the first well region configured to receive a test agent therein and further including biomolecules immobilized therein; a second well region including at least one second well, the second well region configured to receive a sample comprising cells therein and further being horizontally offset with respect to the first well region in a test orientation of the device; and a channel region with biomolecules immobilized therein and including at least one channel connecting the first well region and the second well region with one another. The method also includes forming a surface concentration gradient along a longitudinal axis of the chamber by decreasing the concentration of biomolecules from the at least one first well to the at least one second well; placing a first sample comprising cells in the at least one second well; and monitoring haptotaxis of the cells.

    摘要： The present invention discloses a method of monitoring chemotaxis or chemoinvasion comprising: providing a device for monitoring chemotaxis. The device includes a support member; a top member mounted to the support member by being placed in substantially fluid-tight, conformal contact with the support member. The support member and the top member are configured such that they together define a discrete assay chamber. The discrete assay chamber includes a first well region including at least one first well, the at least one first well being configured to receive a soluble test substance therein; a second well region including at least one second well, the at least one second well being configured to receive a sample comprising cells therein; and a channel region including at least one channel connecting the first well region and the second well region. Preferably, at least one second well is horizontally offset with respect to the first well region in a test orientation of the device. The method further comprises placing the soluble test substance in the at least one first well; forming a solution concentration gradient along a longitudinal axis of the chamber; placing a first sample comprising cells in the at least one second well; and monitoring chemotaxis of the cells.

    摘要： A device for monitoring leukocyte migration is provided. The invention also provides a method of using the device to monitor leukocyte migration in the presence of physiological shear flow and therefore simulate physiological conditions of a blood vessel in vivo. The invention further provides a method of using the device to high-throughput screen a plurality of test agents. The present invention further provides a flexible assay system and numerous assays that can be used to test biological interactions and systems. Laminar flow gradients are employed that mimic gradient situations present in vivo.
