The TriMethyl-Histone H3-K27 Antibody (CAB2363) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, specifically targets the trimethylated form of histone H3 at lysine 27, a crucial histone modification involved in gene regulation and chromatin remodeling. Histone modifications, such as trimethylation of histone H3 at lysine 27, play a critical role in controlling gene expression and cellular functions. The CAB2363 antibody is highly reactive with human samples and has been validated for use in various applications, including Western blot and immunohistochemistry.
This antibody is validated for use in WB, IHC-P, IF/ICC, IP, ChIP, ChIP-seq, ELISA 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.
