Western Blot (WB) of anti-EP300 antibody

Figure 1. Western blot analysis of KAT3B/p300 using anti-KAT3B/p300 antibody (MBS177478).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours.
lane 1: recombinant human kat3b/p300 protein 0.5ng.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-KAT3B/p300 antigen affinity purified polyclonal antibody at 0.5ug/mL overnight at 4 degree C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit with Tanon 5200 system. A specific band was detected for KAT3B/p300 at approximately 50KD.

KAT3B/p300 was detected in paraffin-embedded section of mouse intestine tissue. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1ug/ml rabbit anti-KAT3B/p300 Antibody (MBS177478) overnight at 4 degree C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37 degree C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC) with DAB as the chromogen.

NCBI Summary for EP300

This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. It functions as histone acetyltransferase that regulates transcription via chromatin remodeling and is important in the processes of cell proliferation and differentiation. It mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. This gene has also been identified as a co-activator of HIF1A (hypoxia-inducible factor 1 alpha), and thus plays a role in the stimulation of hypoxia-induced genes such as VEGF. Defects in this gene are a cause of Rubinstein-Taybi syndrome and may also play a role in epithelial cancer. [provided by RefSeq, Jul 2008]

UniProt Comments for EP300

p300: a histone acetyltransferase and transcriptional co-activator that regulates transcription via chromatin remodeling. Acetylates all four core histones in nucleosomes. Related to CPB (CREB-binding protein), and like CPB can stimulate transcription through activation of CREB. Specifically inhibited by the adenovirus oncoprotein E1A. A co-activator of HIF1A (hypoxia-inducible factor 1 alpha), and thus plays a role in the stimulation of hypoxia-induced genes such as VEGF. Mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. Methylated at R580 and R604 in the KIX domain by CARM1, which blocks association with CREB, inhibits CREB signaling and activates the apoptotic response. Also methylated at R2142 by CARM1, which impairs interaction with NCoA2.
