The MonoMethyl-Histone H3-K18 Monoclonal Antibody (CAB20680) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody specifically targets the monomethylated form of histone H3 at lysine 18, a post-translational modification associated with gene activation and transcriptional regulation.Raised in rabbits, this antibody is highly specific and sensitive when detecting monomethyl histone H3 (K18) in human samples. It has been validated for use in Western blot applications, allowing for accurate analysis of histone modifications in different cell types and biological contexts.Histone modifications, such as monomethylation of histone H3 at K18, play a key role in gene expression regulation and epigenetic control.
This antibody is validated for use in WB, IHC-P, IF/ICC, IP, ChIP, ELISA, DB, CUT&Tag 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.
