TESTAGEN 20mg
Testagen 20mg – Research Reference Material
Research Grade • Lyophilised Form • HPLC and Mass Spectrometry Verified • Batch-Specific Documentation
Overview
Peptiology’s Testagen 20mg is a synthetic peptide reference material supplied in lyophilised form for controlled laboratory, analytical and biochemical research.
Testagen, also known as KEDG (Lys-Glu-Asp-Gly), is a defined synthetic tetrapeptide associated with the Khavinson short-peptide bioregulator research series. It has been investigated in experimental research involving tissue-specific gene-expression regulation and molecular interactions.
Its defined four-amino-acid structure makes Testagen suitable for laboratory workflows involving peptide identification, molecular characterisation, analytical method development and biochemical research.
Product Specifications
Product Name: Testagen 20mg
Catalogue Number: Refer to current Peptiology catalogue
Alternative Name: KEDG
Amino Acid Sequence: Lys-Glu-Asp-Gly (KEDG)
Peptide Length: 4 amino acids
Molecular Formula: C₁₇H₂₉N₅O₉
Molecular Weight: Approximately 447.4 g/mol
Form: Lyophilised solid
Purity: ≥99% where confirmed by the applicable batch COA
CAS Number: Refer to batch-specific COA
Analytical Methods: HPLC and mass spectrometry
The definitive purity, molecular identity, molecular weight, salt form and analytical results for each Peptiology batch should always be confirmed against the applicable Certificate of Analysis. Published supplier documentation identifies Testagen as KEDG with molecular formula C₁₇H₂₉N₅O₉ and molecular weight around 447 g/mol.
Storage and Laboratory Handling
Testagen is supplied in lyophilised form to support stability during storage and transport.
Store the unopened material according to the conditions specified in the applicable product documentation and batch-specific Certificate of Analysis. Protect the material from excessive heat, moisture and direct light.
Laboratory preparation should be carried out using suitable research-grade materials, appropriate equipment and documented handling procedures.
Once prepared for laboratory analysis, storage conditions should be determined according to the validated requirements of the relevant research protocol.
Synthesis and Quality Assurance
Our Testagen is supplied as a synthetic peptide reference material with quality-assurance procedures designed to support:
High sequence fidelity
Consistent molecular identity
Reliable batch-to-batch specifications
Traceable analytical documentation
Reproducible research material
Each batch is assessed using applicable analytical techniques such as HPLC and mass spectrometry. A batch-specific Certificate of Analysis is available to support analytical transparency and traceability.
Research Applications
Testagen has been investigated in laboratory research involving:
Peptide identification and characterisation
Molecular and biochemical analysis
Tissue-specific gene-expression research
Peptide–DNA interaction studies
Cellular and molecular research models
Analytical assay development
Experimental studies have investigated KEDG in relation to cellular uptake and interactions with DNA sequences, while broader research into short peptide bioregulators has explored their potential role in tissue-specific molecular regulation. The available evidence remains primarily preclinical and laboratory-based.
These descriptions relate to laboratory and preclinical research contexts and should not be interpreted as claims of therapeutic efficacy or established clinical use.

Important Notice
For laboratory research and in-vitro use only.
This material is not intended for human or animal use, household use, food use or any form of personal application. It is supplied solely as a laboratory reference material for appropriately controlled research environments.
Product specifications, purity, molecular identity, salt form, storage conditions and analytical results should always be verified against the current batch-specific Certificate of Analysis and product documentation.
Reconstitution & Handling
- Recommended solvent Refer to COA / product notes
- Storage Store as directed in documentation
Important reconstitution notice:
Unless the product page, COA, or batch-specific documentation states otherwise, Peptiology peptide products should only be reconstituted using bacteriostatic water supplied by Peptiology.
Peptides are chemically sensitive materials, and reconstitution behaviour can be influenced by the exact diluent used. Different diluents may vary in pH, ionic strength, preservative content, buffering capacity, osmolarity, dissolved gases, and trace impurities. Even small differences in these factors can affect how a peptide dissolves and behaves in solution.
From a chemistry perspective, pH is especially important because it can alter the ionisation state of acidic and basic amino acid side chains. This can change the peptide’s net charge, hydrogen bonding, electrostatic interactions, and hydrophobic association. If the local pH environment is unsuitable, the peptide may show cloudiness, floating particles, clumping, gel-like behaviour, aggregation, or precipitation.
Bacteriostatic water, sterile water, saline, acetic acid water, and buffered solvent systems are not chemically identical. Substituting one for another may change the peptide’s solubility profile, particularly for longer sequences, hydrophobic peptides, modified peptides, or peptides with specific salt forms.
For consistency, reproducibility, and batch comparability, only the recommended diluent system should be used unless an alternative solvent is specifically stated in the product documentation.

- Do not substitute diluents unless specifically instructed.
- Only use Peptiology-supplied bacteriostatic water unless stated otherwise.
- Do not assume all peptides behave the same after reconstitution.
- Visible changes may be caused by diluent incompatibility, pH shift, ionic effects, concentration effects, or peptide-specific solubility behaviour.
- Peptiology cannot verify reconstitution compatibility where non-Peptiology diluents have been used.
