ChemotaxisAssayUsingMicrochemotaxisChambers(ModifiedBoydenChamber)
Overview This assay uses a simple apparatus to study chemotaxis of leukocytes or other migratory cells. The apparatus consists of two multi-well chambers separated by a filter containing pores of uniform size. A solution containing a chemokine or chemotactic factor is placed in the botton chamber and a cell suspension is placed in the upper chamber. Cells can migrate through the pores, across the thickness of th......阅读全文
