Histone macroH2A1.1 antibody (pAb) tested by Western blot.
U2OS cells mock transfected (lane 1) or transfected with tagged macroH2A1.1 (lane 2), macroH2A1.2 (lane 3) or macroH2A2 (lane 4) were probed with Histone macroH2A1.1 antibody at a dilution of 1:1,000.


Histone macroH2A1.1 is a histone H2A variant and one of the three members of the macroH2A family. The three macroH2A proteins contain the C-terminal 'macro' domain in addition to the H2A homologous region. This macro domain may bind poly ADP-ribose and other NAD+ metabolites. The macroH2A1.1 and macroH2A1.2 proteins are produced from alternatively spliced transcripts from the macroH2A1 gene while a second distinct macroH2A gene encodes macroH2A2. In mammals, macroH2A is preferentially localized to the inactive X chromosome and in general is proposed to play a role in repressing gene expression. In mice, macroH2A1 is required for the silencing of endogenous retroviruses.

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
