    InvivoGen mouse igg1 isotype control
    LPS contamination in fimbriae preparations is negligible and does not influence the pro-inflammatory activation of MDMs. A) MDMs were treated for 24 h with purified fimbriae (1 μg/ml) from ATCC 33277 WT (fimbriae WT) and ∆PPAD mutant (fimbriae ∆PPAD) strains, as well as LPS-free fimbriae from both strains; n = 3. B) hMDMs were preincubated for 30 min with control <t>(IgG1)</t> or TLR4-blocking antibody (anti-TLR4), then treated for 24 h with purified fimbriae (1 μg/ml) from ATCC 33277 WT (fimbriae WT) and the ∆ ppad mutant (fimbriae ∆PPAD) strains; n = 3. Levels of IL-6 and IL-8 secretion were subsequently measured. Data are presented as mean ± SEM. ‘ns’ indicates not statistically significant. Statistically significant differences are shown in A) between LPS-free fimbriae and fimbriae without the LPS removal step; in B) between IgG1 and anti-TLR4 pretreated samples.
