Strategies for Enhanced Genetic Analysis of Trace DNA from Touch DNA Evidence and Household Dust
In forensic casework it is often necessary to obtain genetic profiles from crime scene samples that contain increasingly smaller amounts of genetic material, called Low Template DNA (LTDNA). Two examples of LTDNA sources are touch DNA evidence and dust bunnies. Touch DNA refers to DNA that is left …
