Abstract
Method for detecting Ki-ras mutations in exon I, codon 12 to 13 in samples of tissue, tumor tissue, tissue secretions, excretions, expectorates, blood and lymph by two subsequent PCR amplifications comprising a regular PCR amplification and an allele specific amplification and wherein the identification step may comprise a Phast Gel SSCP, characterized in that by a specific selection of oligoprimers in the combination of two PCR amplifications and the Phast Gel identification or in the combination of the said regular PCR amplification and Phast Gel identification produced direct detection of the mutations is produced.
Claims1
A method for detecting Ki-ras mutations in exon 1, codon 12 to 13, in a stool sample, the method consisting of:
- a) amplifying DNA isolated from the stool sample by a single PCR amplification with primers having the sequences set forth as SEQ ID NO:5 and SEQ ID NO:2;
- and
- b) identifying the mutations by SSCP on a 20% homogenous polyacrylamide gel, wherein identification produces a direct detection of the Ki-ras mutations.
