abstract:Differential extraction (also known as differential lysis) refers to the process by which the DNA from two different types of cells can be extracted without mixing their contents. The most common application of this method is the extraction of DNA from vaginal epithelial cells and sperm cells from sexual assault cases in order to determine the DNA profiles of the victim and the perpetrator.
According to the principle of mass conservation, the kineticmodelofSCFE is set upfounded ondifferentialextraction, and the mass transfer in SCFE is analyzed.
