Glavac D, Dean M. Applications of heteroduplex evaluation for mutation detection in illness genes. Many completely different approaches have been used for figuring out recognized mutations. Usually beginning with the polymerase chain reaction (PCR), extra assay steps are performed primarily based on the kind of mutation. Table 5 exhibits examples of a few of the incessantly used strategies as well as their benefits and drawbacks. Here, a short view of some of these techniques is introduced with focus on their purposes.
