Originally identified as an overexpressed antigen in breast carcinoma, TPD52 has since been linked to cancer progression, membrane trafficking, and secretory granule dynamics. The TPD52 antibody is widely used to study tumor biology, exocytosis, and intracellular vesicle regulation.\u003cbr\u003e\u003cbr\u003eTPD52 is encoded by the TPD52 gene located on human chromosome 8q21.13. The protein is approximately 25 kilodaltons and characterized by a central coiled-coil domain that mediates homo- and hetero-oligomerization with other D52-like proteins (TPD52L1 and TPD52L2). This interaction facilitates vesicle docking and fusion processes within the Golgi network and secretory pathway. Expression is highest in epithelial tissues, immune cells, and tumors with high metabolic activity.\u003cbr\u003e\u003cbr\u003eA TPD52 antibody detects a 25 kilodalton band in western blot analysis and reveals diffuse cytoplasmic and perinuclear staining in immunofluorescence assays. TPD52 associates with synaptotagmin-like proteins and small GTPases that control vesicle exocytosis, contributing to regulated secretion in endocrine and immune systems. Its upregulation enhances secretory granule release and cell motility, promoting oncogenic transformation and metastasis.\u003cbr\u003e\u003cbr\u003eIn cancer biology, TPD52 is implicated in cell-cycle progression, lipid storage, and energy metabolism. Overexpression increases tumorigenicity by stimulating AKT signaling and inhibiting apoptosis. Conversely, TPD52 depletion suppresses proliferation and sensitizes cells to chemotherapeutic stress. Clinical studies have identified elevated TPD52 expression in breast, ovarian, lung, and prostate cancers, often correlating with poor prognosis and high metastatic potential.\u003cbr\u003e\u003cbr\u003eBeyond oncology, TPD52 participates in vesicle fusion during immune cell degranulation and insulin granule exocytosis, highlighting its role in both secretory and metabolic regulation. Phosphorylation by casein kinase 2 modulates its subcellular localization and protein-binding properties, linking signaling cues to vesicular transport efficiency.\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\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=TPD52 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=TPD52 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=TPD52 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/TPD52 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=TPD52+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":53047290724717,"sku":"FY12524","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a23919d0-501f-40d0-a20b-944f9fcd1b60.jpg?v=1782237036","url":"https:\/\/www.ebiohippo.com\/products\/tpd52-antibody-tumor-protein-d52-bha17135427","provider":"BioHippo","version":"1.0","type":"link"}
