  • Title: Antihistone antibodies detected by ELISA and immunoblotting in systemic lupus erythematosus and rheumatoid arthritis.
    Author: Costa O, Monier JC.
    Journal: J Rheumatol; 1986 Aug; 13(4):722-5. PubMed ID: 3772919.
    Abstract:
    Antihistone antibodies were sought in sera from patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), melanomas, leukemias and other cancers (particularly breast cancer) by micro-ELISA, using a solution of total histones as antigen. This solution contained H1 and core histones (H2A, H2B, H3 and H4). ELISA was positive in 59.8% of SLE cases, 5.2% of RA cases, 11.1% of melanomas, 13.6% of leukemias and 5.6% of other cancers. Immunoblotting using total histones enabled us to clarify the histone fraction recognized by antihistone antibodies. In SLE, these were mainly anti-H1 and anti-H2B antibodies. In RA, antibodies recognized all histone fractions. However, some sera from patients with RA stained the H4 band more intensely.
