Abstract

The presence of sperm cells is an indicator for differential extraction on sexual assault samples. In general, sperm cells are identified by microscopic analysis; however, this conventional method takes time and effort, even for trained personnel. Here, we present a reverse transcription-recombinase polymerase amplification (RT-RPA) assay targeting sperm mRNA marker (PRM1). The RT-RPA assay requires only 40 min for PRM1 detection and demonstrates a sensitivity of 0.1 μL of semen. Our results indicate that the RT-RPA assay may be a rapid, simple, and specific strategy for screening sperm cells in sexual assault samples.
