HST1, for which the designation HSTF1 was proposed for human gene nomenclature, is a heparin-binding growth factor with significant homology to human fibroblast growth factors and the mouse Int-2 protein. By in situ hybridization, Adelaide et al. (1988) mapped the HST gene to chromosome 11q13. The HST1 protein is a heparin-binding growth factor with significant homology with human fibroblast growth factors and the mouse Int-2 protein.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization (datasheet):\u003c\/strong\u003e Secreted .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTissue details (datasheet):\u003c\/strong\u003e Found in a variety of tissues. Isoform 3 expression is constitutive, while isoform 2 expression correlates with the onset of DNA replication (at protein level). Isoform 2 degradation coincides with the cessation of nuclear DNA replication (at protein level). .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSequence similarities (datasheet):\u003c\/strong\u003e Belongs to the dUTPase family.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommonly studied in contexts related to Cancer,Cardiovascular,Growth Factors,Growth Factors\/Hormones,Oncoproteins,Oncoproteins\/Suppressors,Signal Transduction.\u003c\/li\u003e\n\u003cli\u003eSupports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.\u003c\/li\u003e\n\u003cli\u003eUseful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e Compare relative target abundance and apparent size\/isoforms across samples; interpret bands in light of expected MW and potential PTMs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e Quantify target-positive populations in single-cell suspensions; pair with viability and isotype\/FMO controls conceptually.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-reactivity (datasheet):\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/li\u003e\n\u003cli\u003eUse appropriate positive and negative controls (e.g., KO\/KD, blocking peptide, or isotype controls) to support specificity interpretation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAs a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.\u003c\/p\u003e\u003c!-- Sources (internal):\u003cbr\u003e- Product datasheet fields provided in this catalog row (vendor-supplied).\u003cbr\u003e- UniProt Knowledgebase (general protein annotations): https:\/\/www.uniprot.org\/\u003cbr\u003e- NCBI Gene (general gene-level references): https:\/\/www.ncbi.nlm.nih.gov\/gene\/\u003cbr\u003e--\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53069783728493,"sku":"PA1033","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53070063436141,"sku":"PA1033-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53070063468909,"sku":"PA1033-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53070063501677,"sku":"PA1033-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53070063534445,"sku":"PA1033-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53070063567213,"sku":"PA1033-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53070063599981,"sku":"PA1033-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53070063632749,"sku":"PA1033-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53070063665517,"sku":"PA1033-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53070063698285,"sku":"PA1033-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53070063731053,"sku":"PA1033-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53070063763821,"sku":"PA1033-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/pa1033-1-WB-anti-fgf4-antibody.jpg?v=1772557885","url":"https:\/\/www.ebiohippo.com\/products\/anti-fibroblast-growth-factor-4-fgf4-antibody-picoband-bha21006629","provider":"BioHippo","version":"1.0","type":"link"}
