Histone H2B combines with Histone H2A to form the H2A-H2B heterodimer. Histone H2A is also modified by various enzymes and these modifications have been shown to be important in gene regulation.

  • Highly pure, recombinant protein
  • Mass confirmed by ESI-TOF MS
  • Tested for exonuclease, endonuclease and protease contamination

Histone 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. 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.
