Standardizing a simpler, more sensitive and accurate tail bleeding assay in mice

Figure 1 Setting-up of tail bleeding assay in mice. A: Bleeding assay was performed by amputation of the tail tip which was immediately merged in saline (37°C); B: Photo showing difference in the thickness of blood streams in animals receiving prasugrel at 5 (left) or 0.5 (right) mg/kg per day; C: Starting/stopping bleeding cycles (arrows) observed in a FcRγ^-/- mouse.
