for Histone macroH2A1 antibody (pAb)Immunogen

This Histone macroH2A1 antibody was raised against recombinant protein corresponding to the N-terminal half of mouse macroH2A1.2, so will react with macroH2A1 and the macroH2A1.1 and macroH2A1.2 isoforms.

for Histone macroH2A1 antibody (pAb)Buffer

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

for Histone macroH2A1 antibody (pAb)Background

Histone macroH2A (mH2A) is a histone variant that has a region that is similar to histone H2A but has a unique C-terminal domain (the macro domain, also called the non-histone domain (NHD)) in addition to the histone-like region. mH2A associates with condensed chromatin, including the inactive mammalian female X chromosome, senescence-associated heterochromatin foci, imprinted genetic loci, and regions of chromatin that are CpG methylated. In vitro assays with mH2A have shown that nucleosomes containing macroH2A are resistant to ATP-dependent chromatin remodeling and transcription factor binding, and that macroH2A is capable of repressing the initiation of RNA pol II catalyzed transcription.

MacroH2A1 consists of two isoforms, macroH2A1.1 and macroH2A1.2, that are produced by alternative splicing; they differ by only 30 amino acids in the C-terminal non-histone domain (NHD).

for Histone macroH2A1 antibody (pAb)Storage

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.
