SPT6 is a conserved histone chaperone and transcription elongation factor that couples RNA polymerase II (Pol II) activity to chromatin reassembly. It plays essential roles in transcription elongation, mRNA processing, and maintenance of chromatin integrity during gene expression. SPT6 is expressed in most cell types, with high levels in proliferating tissues and the central nervous system, where active transcription and chromatin remodeling are continuous.\u003cbr\u003e\u003cbr\u003eStructurally, SPT6 is a large nuclear protein (~170 kDa) containing tandem SH2 domains at the C-terminus that mediate direct binding to the phosphorylated C-terminal domain of RNA Pol II. The protein also includes acidic and basic regions that interact with nucleosomes, histones H3\/H4, and elongation factors. SPT6 belongs to the transcription elongation factor family conserved across eukaryotes and forms complexes with other regulators such as IWS1, PAF1C, and FACT to coordinate chromatin structure with RNA synthesis.\u003cbr\u003e\u003cbr\u003eFunctionally, SPT6 promotes nucleosome reassembly behind the elongating RNA polymerase and prevents cryptic transcription initiation within coding regions. It also regulates histone modifications, such as H3K36 methylation, by recruiting SETD2 and other histone modifiers during elongation. In addition, SPT6 influences mRNA splicing and 3'-end processing by stabilizing Pol II on gene bodies. Through its dual role as a histone chaperone and elongation factor, SPT6 ensures faithful transcriptional output and epigenetic stability.\u003cbr\u003e\u003cbr\u003eLoss or dysregulation of SPT6 disrupts transcription elongation and chromatin organization, leading to genomic instability and aberrant gene expression. Mutations have been associated with developmental defects, cancer, and neurodegenerative disorders. SPT6 also participates in transcription-coupled DNA repair and chromatin restoration after stress. Pathway associations include RNA polymerase II transcription, chromatin remodeling, and epigenetic regulation. During development, SPT6 expression supports neuronal differentiation and transcriptional fidelity in proliferating cells.\u003cbr\u003e\u003cbr\u003eThe SPT6 antibody from\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=SPT6 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=SPT6 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=SPT6 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/SPT6 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=SPT6+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047325000045,"sku":"FY13391","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_eab369b4-41da-4d1b-a440-399763df88d1.jpg?v=1782237114","url":"https:\/\/www.ebiohippo.com\/products\/spt6-antibody-supt6h-transcription-elongation-factor-spt6-bha17136292","provider":"BioHippo","version":"1.0","type":"link"}
