Comparison of murine retroorbital plexus and facial vein blood collection to mitigate animal ethics issues

摘要

Body weights and blood collection times. a Body weights of blood collection method in all groups (n = 6/blood collection method) were measured before blood collection. b Blood collection times for the retroorbital plexus (RP) and facial vein (FV) methods for experienced and novice groups. Data are shown as means ± s.d. P values were calculated by two-way ANOVA between the RP and FV methods, with blood collection method in all groups (n = 6/blood collection method). **P < 0.01
