Histone H3 ELISA kits are assays designed to detect the histone protein H3, one of the five types of histones present in eukaryotes. It is phosphorylated in the G2 and M phases of the cell cycle and is the most modified of the histones. Post-translational modifications to histone H3 include phosphorylation of serine or threonine and the attachment of acetyl or methyl groups to lysine/arginine. Histone H3 has been associated with the activation of cell signaling pathways and is important in the study of epigenetics. In humans, histone H3 can be encoded by one of several genes.
