Figure 4 Representative agarose gel picture of polymerase chain reaction amplification (A) and restriction fragment length polymorphism using BstN1 (B) for KRAS codon 12. The arrow represents the 157 bp amplicon and M denotes the DNA marker (50 bp). Lane M represents a DNA marker (50 bp). Lanes 2, 4, 7, 8, and 10 represent the mutant band (undigested) of 157 bp. Lane 1, 3, 6, and 9 represent the wild band (digested) of 128 bp. U represents the undigested band used as mutant control.
