ChIP Validated ChIP-Seq Validated Western Blot Validated

Application Notes

Applications Validated by Active Motif:
ChIP-Seq: 4 µg per ChIP
WB*: 0.5 - 2 µg/mL

For optimal results, we recommend the addition of 0.1% Tween 20 to all blocking solutions to reduce background. Individual optimization may be required.

*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western blot.


This antibody was raised against full length, recombinant human KDM5A.


Purified IgG in 140 mM Hepes, pH 7.5, 70 mM NaCl, 32 mM NaOAc, 0.035% sodium azide, 30% glycerol.


AbFlex® KDM5A antibody (rAb) tested by ChIP-Seq
Chromatin immunoprecipitation (ChIP) was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 25 µg of chromatin from human H727 lung cell chromatin and 4 µg of AbFlex KDM5A antibody. ChIP DNA was sequenced on the Illumina NextSeq and 13 million sequence tags were mapped to identify KDM5A binding sites on chromosome 8. You can view the complete data set in the UCSC Genome Browser, starting at this specific location, here.

AbFlex® KDM5A antibody (rAb) tested by Western blot.
40 µg of HeLa cell nuclear extract was run on SDS-PAGE and probed with AbFlex® KDM5A antibody at 2 µg/ml.

MW: 196 kDa

Specificity of AbFlex® KDM5A demonstrated by Western blot.
500 ng of various FLAG-tagged human full-length recombinant proteins was loaded per lane and probed with KDM5A antibody at 1µg/ml (top panel) or FLAG antibody (bottom panel). KDM5A antibody only detects KDM5A protein; the FLAG antibody shows the presence of all proteins on the blot.

AbFlex® antibodies are recombinant antibodies (rAbs) that have been generated using defined DNA sequences to produce highly specific, reproducible antibodies. Each AbFlex antibody contains a 6xHis Tag, a Biotinylation Tag for enzymatic biotin conjugation using the biotin ligase, BirA, and a sortase recognition motif (LPXTG) to attach a variety of labels directly to the antibody including fluorophores, enzymatic substrates (HRP, AP), peptides, drugs as well as solid supports.

KDM5A Lysine (K)-specific demethylase 5A (KDM5A), also known as Jumonji, AT rich interactive domain 1A (JARID1A), is a histone demethylase that specifically demethylates lysine 4 of histone H3 (H3K4), thereby playing a central role in defining the histone code. KDM5A demethylates trimethylated and dimethylated, but not monomethylated H3K4. It does not demethylate histone H3K9, H3K27, H3K36, H3K79 or H4K20. KDM5A may function to stimulate transcription mediated by nuclear receptors and may be involved in transcriptional regulation of HOX proteins during cell differentiation. Also, KDM5A may be involved in the transcriptional repression of cytokines such as CXCL12. It has been shown to bind directly with the Retinoblastoma (pRb) protein which regulates cell proliferation. KDM5A also interacts with Rhombotin-2 which functions distinctly in erythropoiesis and in T-cell leukemogenesis.
