Applications
ApplicationThis ChIPAb+ Estrogen Receptor α -ChIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.
Key Applications
  • Western Blotting
  • Chromatin Immunoprecipitation (ChIP)
Application NotesChromatin Immunoprecipitation:
Sonicated chromatin, prepared from 3x106 MCF7 cells that are either estrogen starved or b-estradiol treated (100 nM, 45 min.) was subjected to chromatin
immunoprecipitation using 4 mL anti-ERa and the Magna ChIP™ G (Cat.# 17-611) kit Standard Protocol. Successful enrichment of ER associated DNA fragments was verified by qPCR using ChIP Primers TFF1 (pS2) flanking the human TFF1 promoter that contains an ER binding site (Please see figures).
Please refer to the EZ-Magna ChIP™ G (Cat.# 17-409) or EZ-ChIP™ (Cat.# 17-371) kit protocols for experimental details.

Western Blot Analysis:
MCF7cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with anti-ERa (1:1000 dilution). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system (Please see figures).

Entrez Gene Number
Entrez Gene SummaryThis gene encodes an estrogen receptor, a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. Alternative splicing results in several transcript variants, which differ in their 5' UTRs and use different promoters.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P03372 # Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues.
SIZE: 595 amino acids; 66216 Da
SUBUNIT: Binds DNA as a homodimer. Can form a heterodimer with ESR2. Interacts with NCOA3, NCOA5 and NCOA6 coactivators, leading to a strong increase of transcription of target genes. Interacts with NCOA7 in a ligand-inducible manner. Interacts with PHB2, PELP1 and UBE1C. Interacts with AKAP13. Interacts with CUEDC2. Interacts with JARID1A. Interacts with SMARD1. Interacts with SLC30A9 (By similarity). Interacts with HEXIM1 and MAP1S. Interacts with PBXIP1.
SUBCELLULAR LOCATION: Nucleus.
DOMAIN: SwissProt: P03372 Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal steroid-binding domain.
PTM: Phosphorylated by cyclin A/CDK2. Phosphorylation probably enhances transcriptional activity.
SIMILARITY: Belongs to the nuclear hormone receptor family. NR3 subfamily. & Contains 1 nuclear receptor DNA-binding domain.
MISCELLANEOUS: In the absence of ligand, steroid hormone receptors are thought to be weakly associated with nuclear components; hormone binding greatly increases receptor affinity. The hormone- receptor complex appears to recognize discrete DNA sequences upstream of transcriptional start sites.
