Fluorescent oligonucleotide ligation technology for identification of ras oncogene mutations.

Abstract excerpt

A mutation detection strategy based on multiplex PCR followed by multiplex allele-specific oligonucleotide probe ligation was developed to detect single nucleotide substitutions in ras oncogenes, a common genetic abnormality in many human cancers. Mutation-specific probes are synthesized for each possible single-base, nonsilent mutation in codons 12, 13, and 61 of H-, K-, and N-ras oncogenes. Mutations are...
