title: Capillary electrophoresis of a multiplex reverse transcription-polymerase chain reaction to target messenger RNA markers for body fluid identification.
abstract: The analysis of cell-specific mRNA expression is a promising new method for the identification of body fluids. A number of mRNA markers have been identified for the forensically most relevant body fluids: blood, saliva, semen, vaginal secretions, and menstrual blood. Apart from a significant improvement in specificity compared to conventional protein-based methods, other important advantages of body fluid identification by mRNA profiling include the possibility of simultaneously isolating RNA and DNA from the same piece of stain and the ability to multiplex numerous RNA markers for the identification of one or several body fluids. RNA profiling can be incorporated into current DNA analysis pipelines.
