Autoantibodies to histone antigens have been described in patients with idiopathic and drug-induced SLE, rheumatoid arthritis, and other conditions. The presence of autoantibodies to histones are frequently found in several rheumatic disorders (1). In one study, the predominant responses to histones in SLE sera were to H1, H2b, and H3. Marked elevations of binding occurred to H1 and H2b in 33% of patients, while 25% showed higher binding to H3 (2). The same study showed the highest anti-histone reactivity to be in patients with rheumatoid arthritis with vasculitis, while the highest reactivity in SLE sera was in those patients with a history of photosensitivity (3). In diploid eukaryotic cells, the chromatin fibers are about 20nM in diameter. They consist of two major components in equal amounts, DNA and basic proteins called histones.
Catalog #H5110-13
Applications
Suitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 0.5-2.0ug/ml detects 17kD Histone H3 in acid extracted lysates from HeLa cells. Acid-extracted proteins from HeLa cells were resolved by electrophoresis, transferred to nitrocellulose and probed with H5110-13 (0.5ug/ml). Proteins were visualized using an IgG (HRP) goat-anti rabbit and a chemiluminescence detection system.
Recommended secondary antibodiesI1905-28 IgM (HRP) Pab GtxMo
I1905-28A IgM (X-Adsorbed) (HRP) Pab GtxMo
