Arterial occlusion time in B6 and A/J mice. Panels A and B are representative occlusion curves from each genotype. Red arrows indicate duration of ferric chloride application to the carotid. Panel A: B6 mice, Panel B: A/J mice. Panel C: Arterial occlusion time, mean ± SEM of 14–17 mice per genotype. Symbol indicates a significant difference (**P < 0.01) between B6 mice determined with a t-test.
