TIBIAS--a microcomputer-based analysis system for isoelectric focusing and electrophoretic patterns.

A program is described for a computer-aided analysis system for isoelectric focusing (IEF) patterns. This system is primarily aimed at comparing and statistically analyzing large numbers of one-dimensional electrofocusing patterns in the search for specific tumor markers in pancreatic ductal secretions. It is designed to collect raw densitometric data, allow interactive processing, matching and statistical tests, and prepare high-quality plots of data at various stages.
