In zebrafish (Danio rerio), the flt1 gene encodes a transmembrane receptor tyrosine kinase that plays a critical role in vascular development and angiogenesis.\u003cp\u003eZebrafish Flt1 is expressed in endothelial cells and is involved in the regulation of blood vessel formation by modulating VEGF signaling. Unlike its counterpart Kdrl (zebrafish VEGFR-2), which promotes angiogenic signaling, Flt1 primarily functions as a decoy receptor that binds VEGF-A and VEGF-B with high affinity, thereby fine-tuning angiogenic responses during embryogenesis. Zebrafish also express a soluble form of Flt1 (sFlt1), which lacks the intracellular kinase domain and acts as a natural inhibitor of VEGF signaling.\u003c\/p\u003e\n\u003cp\u003eExpression of flt1 in zebrafish is detected early during embryonic development, particularly in developing vasculature such as the dorsal aorta, cardinal vein, and intersegmental vessels. Disruption of flt1 leads to aberrant vessel patterning and excessive endothelial sprouting, highlighting its essential regulatory function in vascular morphogenesis.\u003c\/p\u003e\n\u003cp\u003eDue to the optical transparency of zebrafish embryos and the availability of vascular reporter lines, zebrafish Flt1 serves as a powerful model for studying angiogenesis, vascular remodeling, and the mechanisms of VEGF signaling in vivo. It is also a valuable tool for investigating vascular defects, cancer biology, and responses to anti-angiogenic therapies.\u003c\/p\u003e\n\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\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=FLT1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=FLT1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=FLT1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/FLT1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=FLT1+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53047326572909,"sku":"RZ1183","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_451230b6-896b-43dd-a25c-66cac4cba253.jpg?v=1772019455","url":"https:\/\/www.ebiohippo.com\/products\/zebrafish-flt1-antibody-vegfr1-vegf-receptor-1-bha17136378","provider":"BioHippo","version":"1.0","type":"link"}
