Rac1BRac2−/− mice fail to respond to TNP-conjugated lipopolysaccharide (TNP-LPS). IgM, IgG2b, and IgG3 response to TNP-LPS immunization. Mice were immunized 4 days after the last tamoxifen-injection and bled once a week between day 0 and day 21. Day 0, n = 2 mice per group; day 7, n = 5 mice per group, except nRac2+/− = 6; day 14, n = 5 mice per group, except nWT = 3; day 21, n = 5 mice per group, except nRac2+/− = 3. Statistical analysis done using two-way ANOVA with Sidak’s and Tukey’s tests for multiple comparisons combining all time points. **p < 0.01, ***p < 0.001, ****p < 0.0001. Statistical comparison for IgM: **Rac1B vs WT, ***Rac2+/− vs WT, ***Rac2−/− vs WT, ****Rac1BRac2−/− vs WT. Statistical comparison for IgG2b and IgG3: ***Rac1BRac2−/− vs WT.
