How does MWI eliminate the risk of cross contamination of reference and evidentiary samples?
The MWI Laboratory was specially designed to eliminate the potential for cross contamination between evidentiary and comparative samples. This means MWI has two separate through-puts for evidentiary and comparison samples up to and including PCR. Each through-put has multiple rooms side by side connected by small PASS THROUGHS. Samples move from one room to another UNIDIRECTIONALLY only through these specially designed chambers. In addition, physical separation of pre-amplification and post amplification of DNA avoids any contamination of amplified DNA with exogenous DNA.
