<p>The invention is directed to compositions, methods and kits for diagnosing cancers and tumors correlated with mutations in codons 12 and 13 of human K-RAS using primers that amplify target sequences. The amplified target sequences are then analyzed by any number of mass spectrometric techniques, which data are queried against a database of base composition signatures of K-RAS mutations in codons 12 and 13.</p> |
