Khavinson cardiovascular short-peptide bioregulator
Research documentation
Ask sales for the Cardiogen batch COA and the analytical evidence needed to qualify the material for your study. Confirm the available purity and identity records, lot continuity, handling information, and method requirements before ordering.
Overview
Cardiogen belongs to the Khavinson family of short-peptide bioregulators, assigned within that framework to cardiovascular tissue. The working hypothesis behind the class holds that such peptides operate as endogenous regulators of tissue-specific gene-expression programs; for Cardiogen the nominal targets are cardiomyocytes and associated cardiovascular tissue, where the proposed role is maintenance of cell-cycle equilibrium and structural upkeep during physiological stress. A practical caveat governs the material: across the Russian and Eastern European sources that describe it, Cardiogen is not tied to one invariant amino-acid sequence. It functions more as a class label than as a single defined molecule, so any research protocol should anchor to batch-level identity rather than to the name alone. Ask sales for the COA matched to the offered Cardiogen lot and review the identity information actually recorded there. If a buyer's written procedure requires additional sequence characterization or comparison with a published reference, define that work before quotation. Released strictly for research use only.
Applications & buyer fit
Khavinson short bioregulators — Adamax, Cortagen, Cartalax, Cardiogen, Bronchogen, Crystagen, Prostamax, Vesugen — ship to research labs replicating Russian-school protocols or running comparative tissue-specific peptide-bioregulator studies. The published literature base for this class is concentrated in Russian-language sources; buyers should expect to consult that literature directly for protocol selection. Analytical-packet expectations are the same as any other lyophilised research peptide.
Academic Laboratories
Universities, medical schools, and government research institutes qualifying a reference standard for a method-development or in vivo workflow.
Every lot has its own batch-specific CoA — HPLC purity and MS identity, plus any analytical scope agreed at quote stage — tied to the exact lot you receive.
Review a representative batch CoA before you order, so you can confirm the packet matches what your method or sponsor audit needs.
Supplied strictly as a research reagent to research institutions — not a finished dosage form and not for human administration. Buyer qualification runs at the inquiry stage.

Frequently asked questions
Because upstream preparations sold under this name vary, orthogonal characterization is the only reliable way to know what you have received. ESI-MS or LC-MS establishes the intact molecular mass, which for a defined short peptide should match the sequence stated on the paperwork; RP-HPLC then quantifies chromatographic purity and flags co-eluting or minor components that would signal a mixture rather than one compound. Request that the released documentation report the observed mass alongside the claimed residues, so the analytical numbers and the stated structure can be cross-checked before the material enters any assay.
Treat an unregistered short peptide as characterized only after the batch record supplies the explicit residue sequence together with mass-spectrometric confirmation of that sequence. Absent a CAS number, the certificate itself becomes the sole identity anchor, so it must state the measured purity method, the counter-ion form, and residual-water content, since those shift the true peptide mass per vial and therefore the concentration of any reconstituted stock. Only once identity, purity, and salt/water accounting are documented should the preparation be used as a comparator, and each new lot should be re-verified rather than assumed equivalent.
