Binding
Human Complement Factor B TR-FRET Assay: CVF-Bb complex prepared from purified cobra venom factor (1 uM), recombinant human complement factor B (expressed in drosophila cells and purified using standard methods) and human complement factor D (expressed in E. Coli, refolded and purified using standard methods). CVF-Bb complex at 3 nM concentration was incubated with test compound at various concentrations for 1 hour at room temperature in PBS pH 7.4 containing 10 mM MgCl2 and 0.05% (w/v) CHAPS. Human complement C3 substrate purified from plasma was added to a final concentration of 1 uM. After 1 hour incubation at room temperature, the enzyme reaction was stopped by addition of a cocktail of concentrated pan-protease inhibitors. The product of the reaction, C3a, was quantified by means of an enzyme-linked-immunosorbent assay. IC50 values were calculated from percentage of inhibition of CVF-Bb activity as a function of test compound concentration.
