Product Overview
Clone 21H24 is a rabbit monoclonal antibody that recognizes histone acetyltransferase type B catalytic subunit (gene HAT1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 49.5 kDa, and the supplier reports an observed band at about 45 kDa.
Histone acetyltransferase 1 (HAT1) is a type B histone acetyltransferase that acetylates newly made histone H4 at lysines 5 and 12 before they are assembled into chromatin. It supports chromatin replication and histone supply and has been linked to DNA repair and metabolism. HAT1 is studied in chromatin assembly and epigenetics.
