Reported biological context includes: The alpha-beta heterodimeric T-cell antigen receptor binds antigen in association with major histocompatibility complex proteins on host cell surfaces. These 2 disulfide-linked glycoproteins, TCRA and TCRB are associated on T-cell surfaces with a complex of proteins called CD3(formerly T3).\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eSpatial and single-cell approaches: imaging-based and cytometry workflows increasingly quantify heterogeneity and relocalization rather than only bulk abundance.\u003c\/li\u003e   \u003cli\u003eInteraction-centric biology: IP-based enrichment and proteomics are widely used to define complexes, binding partners, and context-specific interactomes.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eIHC-F: commonly used to measure relative target levels or localization changes in the context of the experimental question.\u003c\/li\u003e   \u003cli\u003eFACS: commonly used to measure relative target levels or localization changes in the context of the experimental question.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eAcross these readouts, differences in signal intensity, localization, or complex enrichment are typically interpreted alongside sample-matched controls and independent evidence to distinguish regulation from technical variation.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eIsoforms, cleavage products, or post-translational modifications can alter apparent molecular weight and subcellular distribution; interpret bands and staining patterns in the context of expected biology and sample preparation.\u003c\/li\u003e   \u003cli\u003eSpecies differences and epitope conservation may affect binding; use matched positive controls and orthogonal evidence when comparing across organisms.\u003c\/li\u003e   \u003cli\u003eControl concepts: include appropriate isotype and secondary-only controls (for imaging), and consider genetic perturbations (knockout\/knockdown\/overexpression) or independent antibodies targeting distinct epitopes to strengthen conclusions.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eEpitope context is defined by the immunogen description; when available, align this with known domains, PTM sites, or family homology to anticipate potential cross-reactivity patterns. As a monoclonal antibody, binding is driven by a single epitope, which can support consistent recognition but may be sensitive to epitope masking by PTMs or conformational changes.\u003c\/p\u003e \u003c!-- Sources (internal): - NCBI Gene search (CD3) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CD3 - Ensembl search (CD3) — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=CD3 - PubMed search (CD3) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CD3 - Reactome pathway search (CD3) — Reactome — https:\/\/reactome.org\/content\/query?q=CD3 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml with 1% BSA and 0.01% sodium azide if reconstituted with 0.2ml sterile 1X PBS \/ 100 ug","offer_id":53043251609965,"sku":"R30014","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_9faef621-5ddf-475a-8065-f64b68a2f33b.jpg?v=1771934428","url":"https:\/\/www.ebiohippo.com\/products\/cd3-antibody-bha17103832","provider":"BioHippo","version":"1.0","type":"link"}
