Cardiogen for Sale: A Comprehensive Research Guide

The search for Cardiogen for sale has grown as researchers investigate this short-chain peptide bioregulator for its potential applications in cardiovascular research. Cardiogen, a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Arg (AEDR), is a molecular tool for probing fibroblast activity, cardiomyocyte survival, and extracellular matrix dynamics in model systems .

Understanding Cardiogen Peptide

Cardiogen is a short biologically active peptide with the sequence H-Ala-Glu-Asp-Arg-OH, corresponding to a molecular formula of C₁₈H₃₁N₇O₉ and a molecular weight of approximately 489 Da . The peptide is a four-amino-acid sequence that promotes β-turn formation and flexible conformational states . Researchers employ Cardiogen in biophysical and mechanistic studies; its compact nature supports high-resolution structural work.

The peptide is typically supplied as a lyophilized powder, with research-grade products demonstrating purity of at least 97-98% when analyzed by high-performance liquid chromatography . Cardiogen’s CAS number is 857267-11-9, and proper storage at -20°C in a dry, desiccated environment protected from light is essential for maintaining peptide integrity .

Mechanism of Action and Research Applications

Cardiac Tissue Research

Cardiogen has been investigated for its potential to support cardiac tissue function. Research suggests its primary activity may involve regulating fibroblast proliferation and modulating cardiomyocyte apoptotic signaling . Studies indicate that Cardiogen may stimulate fibroblast-driven synthesis of extracellular matrix components, including collagen and elastin, thereby supporting structural integrity in myocardial repair contexts.

Cell Proliferation and Survival Studies

The peptide has demonstrated significant effects on cell proliferation in tissue culture models. In a study comparing young and old rats, Cardiogen showed a great stimulating effect on proliferation both in tissues from young and old animals . Immunohistochemical studies demonstrated a decrease of the p53 protein expression by Cardiogen action, which suggests that Cardiogen may inhibit the apoptosis process in myocardial tissue . This dual activity—supporting both fibrosis modulation and cell survival—positions Cardiogen as an intriguing agent for repair-oriented research models.

DNA Interaction Studies

Biochemical research has revealed that Cardiogen does not bind with single-stranded monotonous oligonucleotides and only slightly interacts with certain double-stranded oligonucleotides . However, it interacts with both unmethylated and methylated phage DNA-ethidium bromide complexes more strongly than other tested peptides . Research indicates that Cardiogen can control endonuclease DNA hydrolysis, and this effect may be mediated through interaction with the enzyme rather than direct binding to DNA .

Gene Expression and Epigenetic Research

Beyond direct cellular outcomes, Cardiogen is theorized to support gene regulatory networks. Investigations suggest the peptide may modulate transcriptional activity of genes associated with cellular survival, repair, and matrix remodeling . Studies also suggest that it may support epigenetic markers, such as histone acetylation or methylation, in cardiomyocyte models, thereby altering gene expression over longer periods.

Oxidative Stress Research

Oxidative stress is a key factor in myocardial injury and dysfunction. Investigations suggest that Cardiogen might interact with cellular antioxidant pathways, potentially attenuating the accumulation of reactive oxygen species within cardiomyocytes . By potentially supporting mitochondrial function and redox homeostasis, it appears to support cellular capacity to withstand stressors such as ischemia or metabolic challenges in model systems.

Quality Considerations for Research Peptides Cardiogen for Sale

Purity Standards and Analytical Verification Cardiogen for Sale

For those seeking Cardiogen for sale for research purposes, quality standards are essential. Research-grade Cardiogen should demonstrate minimum purity specifications of at least 97% when analyzed by HPLC, with many suppliers offering products at 98% purity or higher . High-purity research peptides are critical for experimental reproducibility, as impurities from synthesis can confound experimental results.

The certificate of analysis for research-grade Cardiogen should include identity confirmation by mass spectrometry, purity by HPLC, sequence confirmation, and appearance testing.

Documentation Requirements Cardiogen for Sale

Legitimate suppliers providing Cardiogen for sale should offer batch-specific Certificates of Analysis containing HPLC chromatograms and mass spectrometry identity confirmation. Third-party lab accreditation and pre-purchase document access are indicators of reliable sourcing.

Storage and Handling Cardiogen for Sale 

Cardiogen is typically supplied as a lyophilized powder, which helps preserve peptide stability during storage and transportation. Researchers should store lyophilized Cardiogen at -20°C in a dry, desiccated environment protected from light . Upon reconstitution, the peptide should be stored at 4°C and used within a short timeframe to prevent loss of potency.

Repeated freeze-thaw cycles should be avoided to maintain peptide stability. Preparing aliquots of reconstituted Cardiogen for single-use applications preserves compound integrity over extended research periods.

Regulatory Status and Legal Considerations Cardiogen for Sale

Cardiogen for sale for research purposes is classified as a research-use-only product. These compounds are not approved for human use outside of clinical trials and are intended exclusively for in-vitro laboratory research. Researchers must ensure compliance with all applicable regulations regarding the acquisition, handling, and use of research peptides in their jurisdiction.

Conclusion Cardiogen for Sale

Cardiogen for sale represents a significant research investment across multiple scientific disciplines, from cardiac tissue research and fibroblast studies to DNA interaction and oxidative stress investigations. Its unique tetrapeptide structure and dual modulatory potential—coordinating fibroblast matrix synthesis and cardiomyocyte survival signaling—make it a valuable research tool for investigating repair-oriented and regenerative pathways.

For researchers acquiring Cardiogen, understanding the compound’s chemical properties, quality requirements, and pricing factors is essential. High-purity research-grade Cardiogen, stored and handled properly, provides a valuable tool for investigating fundamental biological processes. When evaluating suppliers, researchers should prioritize those that provide comprehensive quality documentation, including HPLC purity verification and mass spectrometry confirmation, to ensure experimental reproducibility and scientific validity.
