Figure 2 Analysis of K-ras mutations at codon 12 (A) and codon 13 (B) in adenoma tissues (T) and paired stool (S) samples. Fragments of 157 bp indicate mutations, and fragments of 128 bp(A) or 125 bp (B) respectively represent wild-type alleles. M: 100 bp ladder marker; P: Positive control; B shows the result that a mutation at codon 13 of K-ras in stool DNA was not observed in tumor counterpart.
