Inhibition of Sclerostin function by antibodies.
(A) Sclerostin-GFP was pre-incubated with Fc or the different Fabs raised against Sclerostin for 30 minutes at room temperature, next the mixtures were added to 293-LRP6 cells for 1.5h at 4°C. After binding the cells were transferred to a 37°C incubator for 30 minutes, next the cells were fixed and confocal images were taken. (B) KS483 cells were affinity labeled with [125I]Sclerostin that was pre-incubated for 30 minutes at room temperature with controls (Fc and aGFP-IgG) or Sclerostin neutralizing antibodies (AbD9097 and aSCL-IgG), followed by chemical crosslinking. Cells were lysed and samples were separated by SDS-PAGE. The radioactive signal was visualized using a phosphorimager screen. (C) KS483 cells were transiently transfected with the BAT-luc reporter construct. The cells were stimulated with conditioned control media (pcDNA CM) or Wnt3a conditioned media (Wnt3a CM), together or without Sclerostin conditioned (SCL CM) media that was pre-incubated with either anti GFP-IgG2a (aGFP-IgG) or anti Sclerostin-IgG2a (aSCL-IgG) for 30 minutes at room temperature. (D) KS483 cells were stimulated with control conditioned media or Wnt3a conditioned media (Wnt3a CM), together or without Sclerostin conditioned media that was pre-incubated with either anti GFP-IgG2a (aGFP-IgG) or anti Sclerostin-IgG2a (aSCL-IgG) for 30 minutes at room temperature. RNA was isolated and AXIN2 mRNA levels were determined by qRT-PCR. (E) KS483 cells were stimulated with the indicated conditioned media, which were pre-incubated with the indicated Fab antibodies. Three days after stimulation cells were fixed and stained for alkaline phosphatase activity. Results were quantified using spectrometry (F).

    • Human anti sclerostin, clone AbD09097_h/mIgG2a specifically recognises human and mouse sclerostin, also known as SOST. Sclerostin is a secreted extracellular matrix protein that is expressed at low levels in bone, bone marrow and cartilage. It may also be detected in other tissues such as kidney and liver. Sclerostin is important in the negative regulation of bone growth with mutations in the sclerostin gene resulting in conditions associated with high bone mass such as sclerosteosis and van Buchem disease. Sclerostin research may facilitate the development of future treatments for diseases associated with bone loss such as osteoporosis (Papapoulos 2011).

      Sclerostin mediates its inhibitory effect on bone formation by directly blocking the Wnt signaling pathway. In addition, it has been reported that sclerostin may associate with intracellular bone morphogenic protein 7 (BMP7), and block its secretion in osteocytes (Krause et al. 2010).

      Clone AbD09097_h/mIgG2a has been demonstrated to block the binding of sclerostin to the Wnt co-receptors, low density lipoprotein receptor-related protein (LRP) 5 and LRP6 on KS483 cells. In a BAT-luc reporter assay, clone AbD09097_h/mIgG2a showed a significant rescue of the inhibition by Sclerostin on the Wnt3a induced BAT-luc activity. Clone AbD09097_h/mIgG2a was also able to rescue the inhibition by sclerostin on Wnt3a-induced AXIN2 mRNA expression and the sclerostin-mediated inhibition of alkaline phosphatase activity induced by Wnt3a (van Dinther et al. 2013).

      Clone AbD09097_h/mIgG2a is a fully human/mouse chimeric antibody, developed from the inhibitory Fab antibody AbD09097(van Dinther et al. 2013).
