Abstract

The contact area between an antibody (Ab) and the antigen (Ag) is called antigenic determinant or epitope. The first step in the characterization of an Ag by using monoclonal antibodies (MAb) is to map the relative distribution of the corresponding epitopes on the Ag surface. The computer program MAPAG has been devised to automatically construct antigenic maps. MAPAG is fed with a binary matrix of experimental data indicating the ability of paired MAb to bind or not simultaneously to the Ag. The program is interactive menu-driven and allows the user an easy data handling. MAPAG utilizes iterative processes to construct and to adjust the final map, which is graphically shown as a 2- or a 3-dimensional model. Additionally, the antigenic map obtained can be optionally modified by the user or readjusted by the program. The suitability of MAPAG was illustrated by running experimental data from literature and comparing antigenic maps constructed by the program with those elaborated by the investigators without the assistance of a computer. Furthermore, since some MAb could present negative allosteric effects leading to misinterpretation of data, MAPAG has been provided with an approximate reasoning module to solve such anomalous situ...Continue Reading
