Detection of B-RAF and N-RAS mutations in human melanoma

Abstract excerpt

BACKGROUND: It is now known that activating point mutations in components of the mitogen-activated protein kinase pathway commonly occur in melanoma. We previously described a method to detect point mutations in heterogenous tissues containing both wild-type and mutant B-RAF and N-RAS genes by using site-directed mutagenesis to introduce new restrictions sites in the cDNA sequence when the specific point...
