Figure Lengend Snippet: Irradiated strains from the MTBC lineages L1, L2, L3, L4S (specialist), L4G (generalist), L5, L6 and H37Rv were incubated with recombinant (r) MBL ( A ), rficolin-2 ( B ), purified (p) C1q ( C ), rficolin-1 ( D ), rficolin-3 ( E ), rMASP-1 ( F ), rMASP-3 ( G ), and rCL-11 ( H ). Complement binding was measured by flow cytometry using specific antibodies and fluorophore-labelled secondary antibodies. Negative controls were processed identically but in the absence of PRM or MASPs. MFI levels indicate the binding after background subtraction and the data represent the means of at least three independent experiments ± SEM.
Article Snippet: Inhibition of MBL and C1q was performed using anti-MBL-inhibitory mAb 3F8 [ ], and anti-C1q mAb clone CLB/C1q85 isotype IgG1 (MW1828, Sanquin, Amsterdam, Netherlands).
