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.
1 mg/ml, 73 µM is calculated using the molar extinction coefficient for Histone H2B (6400) and its absorbance at 280 nm (3,4). 1.0 A280 units = 2.2 mg/ml
