Combine the optical clarity of microfluidics devices with the throughput of transmembrane assays. Each well of an IncuCyte ClearView plate provides an optically clear surface for label-free imaging and analysis of chemotactic cell migration. Cells are added to the upper chamber and chemoattractant to the lower reservoir plate. Chemotactic transmembrane migration is automatically quantified as the cells migrate through laser etched pores (yellow circles) toward chemoattractant. nalyze sensitive cells using a 96-well approach with high reproducibility Capture cell migration or transendothelial migration in real time all from within your incubator. SDF-α mediated chemotaxis of human T cells. () CD3/CD28 activated T-cells were seeded on an ICM coated ClearView plate and migration toward SDF-α was quantified by measuring the loss of cell area on the top of the membrane. (B) ctivated T-cells were also monitored for their ability to migrate through a HUVEC monolayer in response to SDF-α chemoatrractant gradient.
