  7. 5. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Emilie Boson; [2023]
    Nyckelord :Differential lysis; Differential extraction; Sexual assault samples; Sperm cells; Forensic; DNA recovery; DNA profiling; DNA purification; Applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. LÄS MER
