Product Name :
Mouse anti Estrogen Receptor alpha/ERα/ERS1

Description :
| Clone AER304 | Isotype IgG1 | Product Type Primary Antibodies | Units 0.5ml | Host Mouse | Species Reactivity Human | Application Immunocytochemistry Immunoprecipitation Western Blotting

Background :
AER304 is a mouse monoclonal IgG1 antibody derived by fusion of Sp2/0-Ag14 mouse myeloma cells with splenocytes from a BALB/c mouse, immunized with estrogen receptor protein purified from calf uterus.

Source :
Estrogen receptor (ER) is a hormone binding molecule, which belongs to the nuclear hormone family of intracellular receptors. Estrogen receptors exist as alpha and beta forms encoded by separate genes ESR1 and ESR2. ERα and ERβ share a high degree of sequence homology and are activated by the hormone 17β-estradiol and related compounds, including phytoestrogens and xenoestrogens. Both ERα and ERβ function as transcription factors which mediate many of the biological effects of estradiol at the level of gene regulation. Both receptors and are involved in the normal development and function of numerous tissues. Studies also suggest that ER’s may be involved in a range of pathological conditions including cancers, neurodegenerative diseases and cardiovascular disease. <

Product :
Each vial contains 500 µl 0.2 mg/ml purified monoclonal antibody in phosphated buffered saline (PBS) containing 50% glycerol + 0.2% bovine serum albumin (BSA) + 0.02% sodium azide. Formulation: Each vial contains 500 µl 0.2 mg/ml purified monoclonal antibody in phosphated buffered saline (PBS) containing 50% glycerol + 0.2% bovine serum albumin (BSA) + 0.02% sodium azide.

Specificity :
The antibody AER304 is directed against estrogen receptor alpha (ERα) and recognises amino acids residues 120 – 170, an epitope located in the B domain of ERα.

Applications :
The AER304 antibody is suitable for the detection of estrogen receptor alpha by western blotting, immunoprecipitation and immunocytochemistry. In western blotting, the antibody recognises a doublet of approximately 67 kDa in non-reducing conditions. Optimal antibody dilutions for the different applications should be determined by titration.

Storage :
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Caution :
This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. It may contain hazardous ingredients. Please refer to the Safety Data Sheets (SDS) for additional information and proper handling procedures.

Antibodies are immunoglobulins secreted by effector lymphoid B cells into the bloodstream. Antibodies consist of two light peptide chains and two heavy peptide chains that are linked to each other by disulfide bonds to form a “Y” shaped structure. Both tips of the “Y” structure contain binding sites for a specific antigen. Antibodies are commonly used in medical research, pharmacological research, laboratory research, and health and epidemiological research. They play an important role in hot research areas such as targeted drug development, in vitro diagnostic assays, characterization of signaling pathways, detection of protein expression levels, and identification of candidate biomarkers.
