A simplified, 96-well-adapted, ATP luminescence-based motility assay

摘要

Directional motility assays make use of Boyden chambers or Transwell culture inserts with porous membranes that separate cells seeded in the upper chamber from a chemoattractant supplied in a lower chamber. These assays are often time-consuming and are associated with several limitations due to manual counting and inconsistent results; low signal-to-noise ratio and fluorescence interference; and high cost and the need for specific equipment. Here, we describe a simple, direct, and easy ATP luminescence-based motility assay (ALMA), which can be used for 96-well plate quantification.
