{"product_id":"esr1-antibody-sc-f3358","title":"Phospho-Estrogen Receptor α (Ser118) Antibody","description":"\u003ch2\u003eAbout the Target\u003c\/h2\u003e\u003cp\u003eESR1 is a target of interest in many antibody-based workflows. Phospho-Estrogen Receptor α (Ser118) (ERα) is a ligand-activated nuclear hormone receptor that mediates estrogen signaling by regulating transcription of estrogen-responsive genes. Structurally, ERα comprises a modular architecture with an intrinsically disordered N-terminal domain (NTD) containing Ser118, a central DNA-binding domain, and a C-terminal ligand-binding domain. Depending on the literature source, ESR1 may also be discussed as Phospho-Estrogen Receptor alpha (Ser118) and ESR.\u003c\/p\u003e\u003cp\u003eReported cellular context includes p03372, which can matter when signal is compared across treatments or changing cell states. Following ESR1 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.\u003c\/p\u003e\u003ch2\u003eResearch Context\u003c\/h2\u003e\u003cp\u003eESR1 is commonly interpreted in the context of cancer, endocrinology, and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans p03372, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.\u003c\/p\u003e\u003cp\u003eConsider these angles when interpreting target-level changes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003esignal enrichment within p03372 relative to the broader cellular background\u003c\/li\u003e\n\u003cli\u003echanges associated with proliferative state, oncogenic signaling, or treatment response\u003c\/li\u003e\n\u003cli\u003eresponses to hormone-dependent signaling or endocrine feedback context\u003c\/li\u003e\n\u003cli\u003esignal-dependent shifts after ligand, inhibitor, or growth-factor perturbation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eVariant Considerations\u003c\/h2\u003e\u003cp\u003eIf your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for ESR1. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.\u003c\/p\u003e\u003cp\u003eStandardize sampling time, control choice, and downstream analysis thresholds so apparent differences in ESR1 reflect biology rather than handling. When interpreting ESR1, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.\u003c\/p\u003e\u003cp\u003eFor multi-run studies, a shared reference condition can keep ESR1 trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.\u003c\/p\u003e","brand":"Selleck Chemicals","offers":[{"title":"20 µl","offer_id":57578017030489,"sku":"F3358-20UL","price":139.0,"currency_code":"EUR","in_stock":true},{"title":"100 µl","offer_id":57578017063257,"sku":"F3358-100UL","price":289.0,"currency_code":"EUR","in_stock":true},{"title":"2 × 100 µl","offer_id":57578017096025,"sku":"F3358-2X100UL","price":439.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/F3358-IF.png?v=1773601141","url":"https:\/\/absource-diagnostics.myshopify.com\/products\/esr1-antibody-sc-f3358","provider":"Absource Diagnostics","version":"1.0","type":"link"}
