Reported biological context includes: Bcl-XS is the second mRNA species of Bcl-X protein, which encodes a protein that inhibits the ability of Bcl-2 to enhance the survival of growth factor-deprived cells. In vivo, Bcl-XS mRNA is expressed at high levels in cells that undergo a high rate of turnover, such as developing lymphocytes.\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\u003eWestern blot (WB): compare relative abundance\/isoform patterns across conditions and sample types; band shifts may reflect processing or post-translational modification.\u003c\/li\u003e   \u003cli\u003eIHC-P: 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 polyclonal antibody, recognition spans multiple epitopes, which can improve detection across conformations but may broaden background depending on sample context.\u003c\/p\u003e \u003c!-- Sources (internal): - UniProtKB entry (Q07817) — UniProt Consortium — https:\/\/www.uniprot.org\/uniprotkb\/Q07817\/entry - NCBI Gene search (Bcl-XS) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Bcl-XS - Ensembl search (Bcl-XS) — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=Bcl-XS - PubMed search (Bcl-XS) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Bcl-XS - Reactome pathway search (Bcl-XS) — Reactome — https:\/\/reactome.org\/content\/query?q=Bcl-XS --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53043257803117,"sku":"R30334","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a2b8cfa0-6e0f-4ef8-bea1-1bd745119cdf.jpg?v=1771934483","url":"https:\/\/www.ebiohippo.com\/products\/bcl-xs-antibody-bha17104041","provider":"BioHippo","version":"1.0","type":"link"}
