The TriMethyl-Histone H3-K4 Antibody (CAB2357) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, specifically targets the trimethylated lysine 4 residue on histone H3, a modification linked to gene activation and transcriptional regulation.Histone methylation at lysine 4 on histone H3 is an important epigenetic mark that plays a role in regulating gene expression and chromatin structure. The CAB2357 antibody is highly reactive with human samples and has been validated for use in techniques such as immunohistochemistry and chromatin immunoprecipitation assays.By targeting the trimethylated form of histone H3 at lysine 4, researchers can investigate the impact of this specific epigenetic modification on gene expression patterns, cellular differentiation, and development.
This antibody is validated for use in WB, IHC-P, ChIP, ChIP-seq, ELISA, DB applications and has demonstrated reactivity against Human, Mouse, Rat, Other (Wide Range Predicted) samples.

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3.
