Figure 1.

Examples of sequence electropherograms for wild type (WT) and mutant PTEN, PIK3CA, NRAS and BRAF genes in selected NZM cell lines. Black arrows on PTEN electropherogram represent the nucleotide deletion resulting in frameshift of the PTEN transcript. Nucleotide substitutions in PIK3CA, NRAS and BRAF are shown in brackets.
