The Acetyl-Histone H3-K4/K9/K14/K18/K23/K27 Polyclonal Antibody (CAB21295) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, generated in rabbits, is highly specific for detecting acetyl-histone H3 proteins at multiple lysine residues (K4, K9, K14, K18, K23, K27) in human samples. Acetylation of histone H3 is an important epigenetic modification that plays a crucial role in gene regulation, chromatin structure, and cellular processes. The Acetyl-Histone H3 Polyclonal Antibody allows for the detection and analysis of acetylation patterns on histone H3, providing insights into gene expression, DNA replication, and chromatin organization.
This antibody is validated for use in WB, 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. This structure consists of approximately 146 bp of DNA wrapped around a nucleosome, an 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 found in the large histone gene cluster on chromosome 6p22-p21.3.
