Figure 2

Western blotting analysis with representative sera in ELISA. Lanes 1–6: six representative SLE sera which were positive in ELISA and also had strong reactivity with MDM2 recombinant protein in western blotting analysis. Lanes 7–9: three randomly selected NHS had negative reactivity with MDM2 recombinant protein.
