Encoded by the SETDB1 gene on chromosome 1q21.3, this nuclear protein is part of the SET domain-containing family of histone methyltransferases and plays a central role in chromatin remodeling, gene silencing, and genome stability.\u003cbr\u003e\u003cbr\u003eSETDB1 contains a SET domain conferring methyltransferase activity, a methyl-CpG-binding domain (MBD), and a tudor domain that facilitate chromatin targeting. It forms complexes with co-repressors such as KAP1 (TRIM28) and HP1, directing H3K9 trimethylation at retroelements, developmental genes, and repetitive sequences. Through this mechanism, SETDB1 maintains transcriptional repression and contributes to X-chromosome inactivation, embryonic stem cell identity, and defense against endogenous retroviral elements.\u003cbr\u003e\u003cbr\u003eThe SETDB1 antibody is widely used in epigenetics, developmental biology, and cancer research to examine histone methylation and transcriptional silencing. Western blot analysis identifies a 170 kilodalton band corresponding to SETDB1, while immunofluorescence reveals punctate nuclear staining colocalizing with heterochromatin regions. This antibody enables researchers to assess chromatin states, epigenetic modifications, and silencing pathways across diverse cell types.\u003cbr\u003e\u003cbr\u003eAberrant SETDB1 expression and activity have been linked to multiple cancers, including melanoma, glioma, and lung carcinoma, where it promotes oncogenic transcriptional reprogramming and genomic instability. SETDB1 overexpression can also suppress immune responses by silencing interferon-stimulated genes. The SETDB1 antibody provides a precise reagent for studying epigenetic repression, gene regulation, and chromatin-based disease mechanisms.\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\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=SETDB1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=SETDB1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=SETDB1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/SETDB1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=SETDB1+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":53047302357357,"sku":"FY12807","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_f5aa4794-b92d-4386-bab4-6253858d9827.jpg?v=1782237044","url":"https:\/\/www.ebiohippo.com\/products\/setdb1-antibody-histone-lysine-n-methyltransferase-setdb1-bha17135709","provider":"BioHippo","version":"1.0","type":"link"}
