Western Blot Validated Immunoprecipitation Validated

Application Notes

Validated Applications:
IP: 10 µl per IP
WB: 1:500 - 1:1,000 dilution

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 GCN5 antibody was raised against a peptide within the N-terminal region of human GCN5.


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


GCN5 antibody (pAb) tested by immunoprecipitation.

GCN5 antibody (pAb) tested by Immunoprecipitation.
10 µl of GCN5 antibody was used to immunoprecipitate GCN5 from 500 µg of MCF-7 nuclear cell extract (lane 2). 10 µl of rabbit IgG was used as a negative control (lane 1). The immunoprecipitated protein was detected by Western blotting using the GCN5 antibody at a dilution of 1:500.

Detection of GCN5 by Western blot analysis. Nuclear extract of MCF-7 cells (30 µg) probed with GCN5 antibody at a dilution of 1:500.


GCN5 (General control of nutrition 5, KAT2A) is a histone acetyltransferase (HAT) and serves as a transcriptional activator. GCN5 is a component of the SAGA and ATAC complexes, which have histone acetyltransferase activity for histones H3 and H4. GCN5 is required for neural tube closure and embryonic development.

Positive Control

Active Motif's MCF-7 nuclear extract (Catalog No. 36017) can be used as a positive control for GCN5 antibody.


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.
