{"product_id":"cd8alpha-antibody-sc-f2204","title":"CD8α Antibody","description":"\u003ch2\u003eAbout the Target\u003c\/h2\u003e\u003cp\u003eCD8ALPHA is a target of interest in many antibody-based workflows. CD8α (Cluster of Differentiation 8 alpha) is a transmembrane glycoprotein encoded by the CD8A gene and functions as a co-receptor in immune responses. Structurally, CD8α has three main regions: N-terminal extracellular ectodomain: Contains a single immunoglobulin variable (IgV)-like domain and a proline-rich, flexible hinge or stalk region, Transmembrane helix, Cytoplasmic region and forms homodimers (CD8αα) or heterodimers with CD8β (CD8αβ), containing an extracellular immunoglobulin-like domain, a transmembrane region, and a cytoplasmic tail that associates with the Src-family kinase Lck to facilitate T cell receptor (TCR) signaling. Depending on the literature source, CD8ALPHA may also be discussed as CD8a and Lyt-2.\u003c\/p\u003e\u003cp\u003eReported cellular context includes cell membrane, membrane, and secreted, which can matter when signal is compared across treatments or changing cell states. Following CD8ALPHA 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\u003eCD8ALPHA is commonly interpreted in the context of immunology, developmental biology, and infectious disease research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, membrane, and secreted, 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\u003eapparent redistribution between cell membrane, membrane, and secreted across matched conditions\u003c\/li\u003e\n\u003cli\u003econtext differences tied to immune-cell state, activation, or lineage composition\u003c\/li\u003e\n\u003cli\u003estage-dependent patterns during differentiation, morphogenesis, or lineage commitment\u003c\/li\u003e\n\u003cli\u003ehost-response changes during infection or pathogen-associated stimulation\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 CD8ALPHA. 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 CD8ALPHA reflect biology rather than handling. When interpreting CD8ALPHA, 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 CD8ALPHA 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":57577892020569,"sku":"F2204-20UL","price":169.0,"currency_code":"EUR","in_stock":true},{"title":"100 µl","offer_id":57577892053337,"sku":"F2204-100UL","price":379.0,"currency_code":"EUR","in_stock":true},{"title":"2 × 100 µl","offer_id":57577892086105,"sku":"F2204-2X100UL","price":569.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/F2204-wb.gif?v=1773600274","url":"https:\/\/absource-diagnostics.myshopify.com\/products\/cd8alpha-antibody-sc-f2204","provider":"Absource Diagnostics","version":"1.0","type":"link"}
