title: Measurement of cell migration stimulated by interleukin 8: use of ATP chemiluminescence.
abstract: The reliability of methods for the measurement of chemotaxis is a problem which many previous studies have attempted to solve. However, it has recently been shown that the number of cells migrating through a filter can be measured by determining their ATP content by chemiluminescence. We have adapted this method to use microplates with a 24-well format. This allows cells traversing the membranes to be harvested by centrifugation. The modified method has been used to measure the chemotactic activity of interleukin 8 (IL-8) for human polymorphonuclear leukocytes (PMNL). There was a dose response to IL-8, with an optimal concentration of 10(-8) micrograms/ml. The main advantages of this ATP-based cell migration assay were found to be its speed, reproducibility and ease of use.
