Related Product Information for anti-ESR1 antibody
ER alpha (Estrogen receptor alpha; also Estradiol receptor and NR3A1) is a 65-70kD member of the NR3 subfamily, nuclear hormone receptor family of proteins. It is widely expressed, and serves as a strong activator of estrogen-responsive genes. ER-a is normally quiescent and bound to heat-shock proteins and immunophilins. Following b-estradiol binding, it becomes activated, either homodimerizes or heterodimerizes with ER-b, and binds to DNA with multiple co-activators. Major phosphorylation sites exist at Tyr537, Ser167 and Ser118. Phosphorylation at Ser118 regulates ER-alpha's role in transcription and cell growth.

NCBI Description

This 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. [provided by RefSeq]

Product Notes

The ESR1 esr1 (Catalog #AAA624548) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Estrogen Receptor, phosphorylated (S118) (ER, ER-alpha, Estradiol Receptor, Nuclear Receptor Subfamily 3 Group A Member 1, ESR1, ESR, NR3A1) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Estrogen Receptor can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Suitable for use in Western Blot. Dilution: Western Blot: 1ug/ml. Researchers should empirically determine the suitability of the ESR1 esr1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Estrogen Receptor, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
