This HIRA antibody was raised against a GST-fusion protein containing residues 421-729 of human HIRA.


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.


HIRA antibody (mAb) tested by Western blot.

HIRA mAb (Clone WC119.2H11) tested by Western blot.
5 µg of HIRA mAb (Clone WC15) was used to immunoprecipitate HIRA from 500 µg of colcemid-treated U2OS nuclear extract (lane 2). 5 µg of control mouse IgG was also used (lane 1). The immunoprecipitated protein was detected by Western blotting using HIRA mAb (Clone WC119.2H11) at a dilution of 5 µg/ ml.


HIRA (DGCR1, TUP1) is a histone chaperone that preferentially places the variant Histone H3.3 in nucleosomes, replacing canonical Histone H3 during the cell cycle. HIRA is required for the periodic repression of histone gene transcription during the cell cycle and when complexed with ASF1α is involved in the formation of the senescence-associated heterochromatin foci.

Positive Control

Active Motif's HeLa acid extract (Paclitaxel treated) (Catalog No. 36201) can be used as a positive control for HIRA antibody (Clone WC119.2H11).

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with HIRA antibody (mAb).


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.


This product is guaranteed for 6 months from date of receipt.
