Cardiotrophin-1 is a strong inducer of cardiac hypertrophy, exerts cardio-protective effects and plays a role in neuronal growth and differentiation.1,2In neonatal rat, Cardiotrophin-1 has been shown to promote cardiac myocyte survival and to enhance embryonic myocyte proliferation during cardiac chamber development.3 Cardiotrophin-1 increases angiotensinogen gene transcription and induces VEGF expression in cardiac myocytes.4,5 It also induces vessel growth during cardiac remodelling, an effect that may contribute to its cardio-protective properties.In humans, a recent report showed an increase in circulating Cardiotrophin-1 in heart failure.6 A strong correlation between the increased Cardiotrophin-1 and the severity of left ventricular systolic dysfunction was found.7Cardiotrophin-1 is a very potent neurotrophic factor for motoneurons in long-term culture and protects neonatal rat motoneurons from axotomy-induced cell death.2,8 It was able to modulate the synthesis of specific neurotransmitters by cultured neuronal cells,9 and to promote the survival of rat dopaminergic and chick ciliary neurons.10 Recently, the potential for neuroprotection by Cardiotrophin-1 was investigated in animal models characterized by a prominent axonal degeneration.11-13\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eUsing high-specificity ligands, toxins, and engineered peptides to dissect closely related receptor\/channel subtypes and signaling microdomains.\u003c\/li\u003e\n\u003cli\u003ePairing labeled (e.g., fluorescent) proteins\/peptides with advanced imaging to map surface expression, trafficking, and nanoscale organization.\u003c\/li\u003e\n\u003cli\u003eIncreasing emphasis on reproducibility through standardized characterization (identity, purity, and lot QC) and transparent reporting of reagent attributes.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blot: commonly used to compare signal, binding, or functional readouts across conditions without implying a specific protocol.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eAcross these use cases, changes in signal or functional readout are generally interpreted as evidence of differences in target abundance, accessibility, or engagement, but alternative explanations (matrix effects, off-target interactions, or assay artifacts) should be considered.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eAssay context matters: binding assays, functional modulation, and detection workflows can yield different readouts even for the same target system.\u003c\/li\u003e\n\u003cli\u003eTarget complexity: closely related family members, splice variants, and post-translational modifications can influence apparent specificity and potency.\u003c\/li\u003e\n\u003cli\u003eMatrix and sample effects: buffer composition, detergents, and biological matrices may alter stability or apparent activity; interpret with appropriate controls.\u003c\/li\u003e\n\u003cli\u003eControl concepts: include negative controls and orthogonal validation (e.g., genetic perturbation or alternative reagents) to support robust interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt Knowledgebase (UniProtKB) — UniProt Consortium — https:\/\/www.uniprot.org\/ - NCBI Gene — National Center for Biotechnology Information (NCBI) — https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - NCBI Protein — National Center for Biotechnology Information (NCBI) — https:\/\/www.ncbi.nlm.nih.gov\/protein\/ - PubChem — NIH\/NLM\/NCBI — https:\/\/pubchem.ncbi.nlm.nih.gov\/ - IUPHAR\/BPS Guide to Pharmacology — IUPHAR\/BPS — https:\/\/www.guidetopharmacology.org\/ - RCSB Protein Data Bank (PDB) — RCSB PDB — https:\/\/www.rcsb.org\/ - NCBI Bookshelf — NIH\/NLM — https:\/\/www.ncbi.nlm.nih.gov\/books\/ --\u003e","brand":"Alomone Labs","offers":[{"title":"Default Title","offer_id":53073012392301,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/C-200_117.gif?v=1772699873","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-cardiotrophin-1-protein-bhp21300026","provider":"BioHippo","version":"1.0","type":"link"}
