Denaturation mapping (original) (raw)

Denaturation Mapping is a form of optical mapping, first described in 1966. It is used to characterize DNA molecules without the need for amplification or sequencing. It is based on the differences between the melting temperatures of AT-rich and GC-rich regions. Even though modern sequencing methods reduced the need for denaturation mapping, it is still being used for specific purposes, such as detection of large scale structural variants.
