Product Overview
This rabbit polyclonal antibody recognizes histone-lysine N-methyltransferase SUV39H2 in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 46.7 kDa, and the supplier reports an observed band at about 47 kDa.
SUV39H2 (KMT1B) is a histone methyltransferase that converts monomethylated H3K9 into H3K9me3, a mark that recruits HP1 proteins. Together with SUV39H1 it establishes constitutive heterochromatin at pericentric and telomeric regions and supports DNA methylation of pericentric repeats. SUV39H2 is expressed mainly in the testis.
