The comparison was carried out on 62 examples of genomic DNA extracted from frozen colon carcinomas, which underwent manual dissection. The results obtained in two attempts were consistent in 95,2% (N=59). Specificity and sensitivity of K-ras mutations detection using «KRAS-7M» set were 100 and 96,4% respectively, and 94,1 and 100% respectievly using PCR/SSCP/AСRS/ automatic sequencing. False positive results were absent when detecting with «KRAS-7M» and accounted for 2 cases (5,9%) when using PCR/SSCP/ AСRS/automatic sequencing. The only false negative response (3,6%) was obtained analyzing mutations using «KRAS-7M».</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic>Проведено сравнение двух подходов для анализа соматических точечных мутаций в кодонах 12 и 13 гена K-ras: методов ПЦР/SSCP/AСRS/</italic><italic>секвенирования и аллель-специфической ПЦР в режиме реального времени (отечественный коммерческий набор «KRAS-7M»).
