BRD4 antibody (pAb) tested by ChIP.
Chromatin immunoprecipitation (ChIP) was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 10 µg of chromatin from TNF-α treated HT-29 colorectal adenocarcinoma cells and 5 µl BRD4 antibody. ChIP DNA was used in qPCR with the control primer pairs or gene-specific primer pairs as indicated. Data are presented as Binding Events Detected per 1000 Cells using Active Motif's Epigenetic Services normalization scheme which accounts for primer efficiency and the amount of chromatin used in the ChIP reaction.

for BRD4 antibody (pAb)Background

BRD4 (Bromodomain-containing protein 4, aka HUNK1) is a chromatin-associated protein with two bromo domains that binds acetylated histone H3 and H4. BRD4 is homologous to Xenopus MCAP, and like MCAP, BRD4 associates with chromosomes during mitosis, predominantly in the non-centromeric regions. A chromosomal aberration involving BRD4 (producing a BRD4-NUT fusion protein) is found in a rare, aggressive, and lethal carcinoma arising in midline organs of young people. BRD4 is involved in the expression of extracellular matrix gene expression, and its misregulation may be involved in breast cancer progression.

for BRD4 antibody (pAb)Positive Control

Active Motif's HeLa nuclear extract (Catalog No. 36010) can be used as a positive control for BRD4 antibody.

for BRD4 antibody (pAb)qPCR Primers

Active Motif's Human Negative Control Primer Set 1 (Cat. No. 71001) has been validated for performing qPCR and endpoint PCR when this antibody has been used for ChIP on human samples.

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits.

for BRD4 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.

for BRD4 antibody (pAb)Guarantee

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

This product is for research use only and is not for use in diagnostic procedures.
