THE AEROSPACE CORPORATION SUGGESTED THAT IF THE PRESENT SYSTEM OF SMALL LOCAL U.S. CRIME LABORATORIES IS TO BE CONTINUED, IT WILL BE NECESSARY TO DEVELOP RAPID AND/OR SIMULTANEOUS ELECTROPHORETIC SEPARATION AND IDENTIFICATION OF SEVERAL SELECTED ENZYME/PROTEIN SYSTEMS IN ORDER TO PROMOTE MORE EXTENSIVE BLOODSTAIN ANALYSIS. THIS STATED NEED LED TO THE CURRENT AEROSPACE BAS PROGRAM. MOST ELECTROPHORETIC SEPARATIONS OF ENZYMES AND PROTEIN SYSTEMS IN FORENSIC WORK ARE NOW PERFORMED ON STARCH GEL, EXCEPT FOR HEMOGLOBIN AND HAPTOGLOBIN. THE GEL METHODS REQUIRE LONG RUN TIMES, INCONVENIENCE, AND POSSIBLE ERROR IN PREPARING FRESH SUBSTRATES BEFORE EACH RUN. THE BAS PROCEDURE INVOLVED SIMULTANEOUS ANALYSIS OF EIGHT CONSTITUENTS ON THREE PLATES. HOWEVER, A CRITICAL EVALUATOR CONSIDERS THIS INNOVATION TO BE AN ADDED COMPLICATION TO AN ALREADY COMPLEX ANALYTICAL PROCEDURE. EXTENSIVE TECHNICAL DOCUMENTATION ON THE BAS PROJECT IS PROVIDED.
