Module 4 :: Intro To the Lab
Topic 1 :: History and Development of Forensic DNA Analysis
DNA Typing—DQα (DQA1)/ Polymarker
The first forensic application of PCR used the HLA DQ-alpha (DQA1) system which was expanded to include additional genetic systems called
Polymarker™ (PM).
Although
DQa/Polymarker
was faster and more sensitive than RFLP, results were less discriminating. For example, matching profiles might be found in one in several thousand people. In RLFP, the match could be one in several million.
