SIN3B functions in concert with its paralog SIN3A to coordinate gene silencing, differentiation, and cell cycle control. The SIN3B antibody is widely used in epigenetics and transcriptional regulation research to examine HDAC-dependent gene repression.\u003cbr\u003e\u003cbr\u003eSIN3B is encoded by the SIN3B gene on human chromosome 19p13.11. The protein is approximately 150 kilodaltons and contains multiple paired amphipathic helix (PAH) domains that mediate interactions with transcription factors and chromatin-modifying enzymes. SIN3B serves as a scaffold that assembles HDAC1, HDAC2, RBBP4\/7, and other corepressors into multiprotein complexes targeting specific promoters.\u003cbr\u003e\u003cbr\u003eThe SIN3B antibody detects a 150 kilodalton band by western blot and shows nuclear localization by immunofluorescence. Through recruitment of HDAC complexes, SIN3B deacetylates histones H3 and H4, resulting in chromatin compaction and transcriptional repression. It also interacts with transcription factors such as E2F4, MAD, and REST, enabling context-dependent regulation of genes involved in proliferation, senescence, and neuronal development.\u003cbr\u003e\u003cbr\u003eSIN3B plays key roles in differentiation, acting as a switch from proliferation to quiescence. Knockdown of SIN3B leads to uncontrolled growth and defective chromatin silencing, while overexpression suppresses oncogenic transcription programs. Altered SIN3B function has been implicated in cancer, diabetes, and neurodevelopmental disorders due to disrupted epigenetic control.\u003cbr\u003e\u003cbr\u003eAs a master regulator of chromatin remodeling, SIN3B integrates multiple signaling pathways to maintain transcriptional balance.\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\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\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=SIN3B - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=SIN3B - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=SIN3B - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/SIN3B - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=SIN3B+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":53047291838829,"sku":"FY12547","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_3470e08a-1ade-41dc-bf60-9baf83c31357.jpg?v=1782237015","url":"https:\/\/www.ebiohippo.com\/products\/sin3b-antibody-paired-amphipathic-helix-protein-sin3b-bha17135450","provider":"BioHippo","version":"1.0","type":"link"}
