The diagnostic 235-bp insertion within the ashRab27a transcript is found in homozygous form in both C3H/HeSnJash/ash and a/a, ash/ash mutant mice.
RT-PCR amplification of kidney RNA produces a 710-bp product in normal C3H/HeSnJ mice and a 945-bp product in both ashen mutants. The 1 Kb+ size markers (GibcoBRL, Carlsbad, CA) and PCR products were detected by ethidium bromide staining.
