MED28 plays essential roles in gene expression, cytoskeletal organization, and signal transduction. The MED28 antibody is widely used in transcriptional regulation, cancer, and developmental biology research to study Mediator function and signaling integration.\u003cbr\u003e\u003cbr\u003eMED28 is encoded by the MED28 gene located on human chromosome 4q27. The protein is approximately 178 amino acids long and localizes to both the nucleus and plasma membrane. MED28 interacts with other Mediator complex subunits as well as cytoskeletal proteins, suggesting dual functions in transcriptional control and cell structure regulation. Its nuclear role involves recruitment of RNA polymerase II to promoters and modulation of gene-specific transcriptional activation.\u003cbr\u003e\u003cbr\u003eThe MED28 antibody detects a 22 kilodalton band by western blot and shows nuclear and cortical cytoplasmic staining. MED28 acts as a scaffold linking the cytoskeleton to transcriptional machinery, coordinating extracellular signals with gene expression. It associates with receptor tyrosine kinases and small GTPases, influencing actin organization and cell migration.\u003cbr\u003e\u003cbr\u003eFunctionally, MED28 contributes to development and differentiation by regulating transcription factors involved in lineage commitment. Dysregulation of MED28 expression has been linked to various cancers, including breast and gastric carcinoma, where it enhances proliferation and motility. MED28 also participates in smooth muscle differentiation and cardiovascular development, underscoring its diverse physiological roles.\u003cbr\u003e\u003cbr\u003eThrough its integration of signaling and transcriptional regulation, MED28 serves as a nexus between cellular structure and gene expression.\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=MED28 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=MED28 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=MED28 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/MED28 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=MED28+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":53047294853485,"sku":"FY12612","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_6a309a41-9e92-4472-ad88-b139dbe661f2.jpg?v=1782237028","url":"https:\/\/www.ebiohippo.com\/products\/med28-antibody-mediator-complex-subunit-28-bha17135515","provider":"BioHippo","version":"1.0","type":"link"}
