Abstract

This triplex qPCR assay quantifies and identifies the presence of as little as 0.4 pg of human, feline and canine DNA in a mixed sample [ [1] ]. The assay did not include an Internal Positive Control (IPC) due to the three-dye limit in the Applied Biosystems 7300 machine. The assay is now modified to include an IPC using the 7500 Fast Real Time PCR system. 1 figure and 3 references (publisher abstract modified)
