ACDAS: an automated chemotaxis data acquisition system.

An automated system (ACDAS) for rapid collection and analysis of data from leading front chemotaxis assays is described. ACDAS automatically computes (1) net cell migration from operator-entered end point signals and (2) means and standard errors of the mean from data sets of user-determined size. ACDAS reduces data collecting and processing time by more than 50% compared to manual methods. Other applications of ACDAS are discussed.
