Limit of detection of T. cruzi in açai samples with primers Tc189F/Tc189R. T. cruzi DNA (from 75 pg to 2.4 pg) was mixed with 240 ng of açai DNA before the PCR assay using Tc189F/189R primers. Lane 1: sterile water (negative control); Lane 2: T. rangeli DNA (5 ng); Lane 3: Açai without T. cruzi (negative control); Lane 4: 100 bp DNA ladder. T. cruzi DNA: Lane 5: 75 pg; Lane 6: 45 pg; Lane 7: 24 pg; Lane 8: 15 pg; Lane 9: 9 pg; Lane 10: 3 pg; Lane 11: 2.4 pg
