Abstract
Clonogenic assay is one of the most sensitive assays, widely used to evaluate the effects of antineoplastic agents in vitro. A computer program was developed on an IBAS 2.0 Image Analysis System for automated quantiation of cell colonies and clone area on Petri dishes. The sensitivity of the clonogenic assay can be greatly increased by evaluating the mean area of the clones. The program gives an objective, accurate and fast evaluation of large samples. It is simple to use and offers a high degree of flexibility. Special algorithms and techniques have been implemented for good quantitation of both connected and well-separated colonies and to reduce the background noise and the general error rate. The principles and solutions presented are applicable to any other image analysis system.
