The following might be of some use to you:

R.G.H. Cotton (1993) Current methods of mutation detection.
Mutation Research 285: 125-144.  The review covers the methods used for detection
of unknown mutations including the ribonuclease, denaturing gradient-gel
electrophoresis, carbodiimide, chemical cleavage, single-strand conformation polymorphism,
heteroduplex and sequencing methods.
