microRNA array data for forensically relevant body fluids samples

Identifying the type and origin of biological samples left at a crime scene is crucial in forensic investigations as it can provide important clues for crime scene reconstruction and linkages between victim/perpetrator/scene. MicroRNAs (miRNAs) are considered to be more stable than mRNA due to their small size and protection by protein and have been demonstrated to be a viable tool for body fluid identification in forensic casework. To screen reliable body-fluid specific miRNAs, ten arrays were performed in five body fluids (peripheral blood, menstrual blood, saliva, semen and vaginal secretion). Two arrays were carried out for each body fluid: three samples for the first and the other two for the second (for menstrual blood, the second array detected three samples). 26 samples: five peripheral blood, five vaginal secretion, five saliva, five semen and six menstrual blood were used in this study. Two arrays were carried out for each body fluid: three samples for the first and the other two or three for the second.
