Figure 4From: RNA Recognition Motif (RRM) of La/SSB: The Bridge for Interparticle Spreading of Autoimmune Response to U1-RNPAssessment of the reactivity of sera before and after affinity purification of anti-pep145–164 antibodies. Depletion of anti-pep145–164 antibodies eliminated the anti-U1-RNP reactivity of immunized rabbit serum (wk 13) but not the anti-U1-RNP reactivity of patient #1 serum. All sera and flowthroughs were diluted properly to contain approximately 15 µg/mL of IgG.Back to article page
