Abstract
mRNA profiling is a promising new method for the identification of body fluids from biological stains. A multiplex reverse transcription endpoint PCR method was adapted for the identification of blood, saliva, semen, vaginal secretions and menstrual blood. For specificity, sensitivity and suitability to biological stains the endpoint PCR method was satisfying. Up to 15 months old stains were shown to be suitable for mRNA profiling. In addition a realtime PCR assay was tested for sensitivity with blood and semen samples, providing comparable results to endpoint PCR or enzymatic tests.
