Contamination is a serious concern when working with low quantity DNA samples. LEECG maintains a laboratory dedicated to low quantity DNA samples that is spatially separated from our other DNA facilities. In this laboratory we use:
•UV light sterilization
•10% bleach solution
‐All bench top surfaces
All DNA extractions and PCR reactions are monitored via inclusion of negative controls to test for contamination of reagents.
No forms of high quality DNA extracts or PCR products are allowed into this laboratory.
All of these measures help to minimize contamination of low quantity DNA samples.
