Autoantibody to MDM2: A Potential Serological Marker of Systemic Lupus Erythematosus

Figure 4

Titer of autoantibody against p53 in human sera by ELISA. The range of antibody titers to p53 was expressed as optical density (OD) obtained from ELISA. The mean + 2SD of NHS was shown in relationship to all serum samples. Titer of anti-p53 in SLE serum was much higher than that in NHS (). The cutoff value line for positive samples is indicated in the figure.
