Effects of ultracentrifugation on rCS-induced analgesia in CIPN mice. (A) Schematic of ultracentrifugation (100,000 x g, 120 min, 4°C). (B, C) Von Frey tests for paw withdrawal threshold (B) and withdrawal frequency (C). Ultracentrifuged rCS (U-rCS) showed significantly decreased analgesic effects versus ACS for all measured timepoints up to 28 days following intrathecal injection in CIPN mice. Intrathecally injected ultracentrifuged rNCS (U-rNCS) was used as control. *p<0.05, **p<0.01, ****p<0.001, **p<0.0001, n=5 per group, two-way ANOVA, followed by Bonferroni posthoc test. Male donors and receivers were tested.
