DescriptionHistone H2B combines with Histone H2A to form the H2A-H2B heterodimer. Two H2A/H2B heterodimers interact with an H3/H4 tetramer to form the histone octamer. (1,2) Histone H2B is also modified by various enzymes and can act as a substrate for them. These modifications have been shown to be important in gene regulation.Molecular Weight (kDa)13.8 kDaFormulation20 mM sodium phosphate, 300 mM NaCl, 1 mM EDTASourceExpressed in E.coli expression systemSize50 µgStorage Temp & ConditionsStore stock solution at -20°C.
