differential ?

Hi there. I am a Forensic Serologist. We refer to the term "Differential extraction " when a semen stain is extracted in parts so that the epithelial (female) cells are separated from the sperm (male) cells in order to generate clean DNA profiles.

Is that what you are asking about?
