title: Kras amplicon sequencing of urethane-induced mouse lung tumor
design: RNA was extracted from urethane-induced lung tumors, reverse transcribed into cDNA, and Kras exon 1 to exon 3 was amplified from this cDNA; alternatively, DNA was extracted from urethane-induced lung tumors and Kras exon 1 or exon 2 was amplified from the DNA separately
