{"product_id":"biolegend-648843","title":"Biolegend, 648843, Purified anti-Estrogen Receptor alpha Antibody, 100μg","description":"\u003cp\u003eEstrogen receptor alpha is a nuclear hormone receptor that functions as a transcription factor activated by the hormone estrogen. Upon binding estrogen, ESR1 translocates to the nucleus where it binds to estrogen response elements in the DNA to regulate gene expression. It plays a crucial role in the development and maintenance of reproductive tissues, as well as in bone density, cardiovascular function, and behavior. ESR1 is also a key player in the pathogenesis of hormone-sensitive cancers such as breast, cervical and uterine cancer, where it influences tumor growth and progression.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nImmunogen: Recombinant protein corresponding to a fragment of the N-terminus of human Estrogen Receptor alpha, including the DNA binding domain.\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: IHC-P - Quality tested WB - Verified\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5.0 - 10.0 µg\/mL is suggested. For western blotting, the suggested use of this reagent is 0.25 - 0.5 µg\/mL. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nAdditional Product Notes: For use in immunohistochemistry on formalin-fixed paraffin-embedded tissue (IHC-P), it is recommended to perform antigen retrieval using either Citrate Buffer, 10X (Cat. No. 420902) or Tris-EDTA pH 9.0 Antigen Retrieval Buffer (10X) (Cat. No. 422704). Tris-EDTA pH 9.0 may result in slightly brighter signal.\u003cbr\u003e\nRRID: AB_3720561 (BioLegend Cat.
