Product Overview

Testagen Bioregulator, identified by the amino acid shorthand KEDG, is a short-chain synthetic tetrapeptide that has attracted sustained interest in peptide bioregulator research. Originally investigated within the framework of tissue-specific gene regulation studies, KEDG belongs to a well-characterised class of short peptide bioregulators that have been the subject of peer-reviewed scientific inquiry. The Peptide Store supplies this compound at the highest commercially available purity grade, making it a preferred choice for researchers seeking to buy Testagen Bioregulator online with confidence in analytical traceability and batch consistency.

Peptide Structure & Amino Acid Sequence

Testagen Bioregulator is a tetrapeptide composed of four amino acid residues arranged in the following sequence: Lys-Glu-Asp-Gly (KEDG). This linear sequence — Lysine, Glutamic Acid, Aspartic Acid, and Glycine — defines its classification as a short peptide bioregulator. The compact four-residue architecture is characteristic of peptide bioregulators studied for their potential interactions with nucleic acid structures and tissue-specific regulatory pathways in endocrine research models. The defined sequence enables precise analytical verification and supports reproducibility across experimental protocols.

Purity & Analytical Verification (HPLC & MS)

Every vial of Testagen Bioregulator supplied by The Peptide Store achieves a minimum purity of ≥99% as determined by HPLC-MS (High-Performance Liquid Chromatography coupled with Mass Spectrometry). This dual-method analytical approach confirms both the chromatographic purity profile and the precise molecular identity of the compound. HPLC quantifies the relative abundance of the target peptide against any detectable impurities, while MS provides definitive molecular weight confirmation aligned with the theoretical value of 447.2 g/mol for C₁₇H₂₉N₅O₉. Researchers can order now with assurance that each batch meets or exceeds the stated specification.

Quality Control & Lyophilisation Integrity

Testagen Bioregulator undergoes comprehensive third-party quality control testing prior to release. Each production batch is independently verified by accredited analytical laboratories, with testing encompassing purity assessment, heavy metals screening, and endotoxin (LAL) evaluation. A Certificate of Analysis (COA) is issued per batch and is available upon request. The lyophilisation process is validated to preserve peptide structural integrity, minimise moisture content, and ensure long-term stability under appropriate storage conditions. The Peptide Store maintains strict batch traceability so that researchers can correlate experimental results directly to documented analytical data.

Safety, Handling & Laboratory Precautions

Testagen Bioregulator is supplied exclusively for in vitro laboratory research use by trained scientific personnel. Standard laboratory safety protocols must be observed at all times when handling this compound. Appropriate personal protective equipment (PPE) — including laboratory coat, nitrile gloves, and eye protection — should be worn. This material should be handled in a controlled laboratory environment in accordance with applicable institutional biosafety guidelines. This compound is not evaluated for safety in humans or animals and must not be used outside of a properly equipped research setting.

Reconstitution, Packaging & Storage

Testagen Bioregulator is supplied as a lyophilised powder in a sealed, sterile vial. Reconstitution methodology, solvent selection, and working concentration preparation are the sole responsibility of the qualified end researcher and must be determined in accordance with the specific experimental protocol. For long-term stability, the lyophilised product should be stored at −20°C in a dry, dark environment, away from repeated freeze-thaw cycles. Short-term storage at +4°C is acceptable for active research periods. Once reconstituted, aliquoting and immediate use or appropriate cold-chain storage is recommended per standard peptide handling practice.

Intended Research Use & Market Positioning

Testagen Bioregulator (KEDG) is positioned as a high-purity research tool for scientists investigating short peptide bioregulators, tissue-specific gene expression models, endocrine regulatory pathways, and related fields of molecular biology and gerontology research. The compound’s well-defined tetrapeptide sequence, high analytical purity, and documented research background make it a compelling subject for in vitro mechanistic studies.
