This Mi-2B antibody was raised against a recombinant protein corresponding to amino acids 22-155 of mouse Mi-2 beta.


Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

Mi-2β (Mi-2beta, CHD4, chromodomain helicase DNA-binding protein 4) represents the major Mi-2 isoform present in the complex Mi-2/NuRD. This complex is a multi-subunit protein complex containing both histone deacetylase and nucleosome-dependent ATPase subunits. Current models predict that this complex functions primarily in transcriptional repression. In addition to the ATPase domain, Mi-2 beta contains a chromodomain and two PHD domains. Mi-2 beta interacts with BRG-1, a component of the SWI/SNF complex, and the RET finger protein (RFP).

Positive Control

Active Motif's HeLa nuclear extract (Catalog No. 36010) can be used as a positive control for Mi-2 beta antibody.
