Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of histone H3 in which Arg17 is citrullinated.
Background
The nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), is the primary building block of chromatin. Histone posttranslational modifications, such as methylation, acetylation, ubiquitination, and citrullination, influence chromatin accessibility and regulate gene expression (1). Histone citrullination is carried out by protein arginine deiminases (PADs), which convert positively charged arginine residues into neutral citrulline (2). Histone citrullination affects the binding of histone reader proteins to chromatin, and it is associated with both transcriptional activation and repression (3-5). Histone citrullination is also a major marker for NETosis, which is a programmed cell death mechanism carried out by neutrophils (6). De-regulation of NETosis is associated with multiple autoimmune diseases, including rheumatoid arthritis (RA) and lupus (7,8). Histone hypercitrullination via PAD4 may also play a role in the progression of various cancers, including multiple myeloma (MM), acute myeloid leukemia (AML), lung cancer, and hepatocellular carcinoma (HCC) (9-12).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
