Serum Bactericidal Assay (SBA) titers against 44/76-SL wild-type in pooled sera from C57bl/6 mice pre-injected with 800 μg/ml hfH or hSA, 14 days following immunization with 5 &mu:g of nOMVlpxl1 or nOMVdis. C. Individual SBA titers against 44/76-SL, dots represent individual animals D. Individual ELISA titers against rfHbp induced after one dose of H44/76Lpxl1 OMV in mice pre-injected with hfH or hSA, *p = 0.016, not all sera were available. C, D dots represent individual animals, the geometric mean and 95% confidence interval are represented as horizontal bars.

| Mouse anti Human Complement Factor H antibody, clone OX-23 recognizes intact human serum complement protein factor H, also known as H factor 1. Complement factor H is a 1213 amino acid ~155 kDa secreted glycoprotein bearing multiple disulphide bonds and is involved in the deactivation of C3b and dissociation of C3 convertase in the alternative complement pathway. Mouse anti Human Complement Factor H antibody, clone OX-23 also recognizes a ~43-49 kDa truncated form of factor H present at low level (1-5ug/ml) in plasma and urine. Mutations in the CFH gene can lead to the development of Complement Factor H deficiency (CFHD) which can be asymptomatic, present with recurrent bacterial infections or renal failure (Ault et al. 1997). Mutations can also lead to development of Basal laminar drusen (BLD), the deposition of extracellular deposits accumulating below the retinal pigment epithelium on Bruch membrane which can ultimately lead to vision loss (Boon et al. 2008). Additionally, mutations in the CFH gene can lead to increased susceptibility to Hemolytic uremic syndrome atypical 1 (AHUS1) or Macular degeneration, age-related, 4 (ARMD4). Mouse anti Human Complement Factor H antibody, clone OX-23 has been used successfully for the determination of levels of bound murine factor H in a sandwich ELISA in conjunction with Sheep anti Human Factor H antibody (4400-9504 ) as a capture reagent (Daniels-Treffandier et al. 2016). |
