Testagen (Lys-Glu-Asp-Gly) is a synthetic tetrapeptide bioregulator studied for nuclear DNA-binding activity and pituitary-thyroid axis effects in animal models. Fedoreyeva et al. (Biochemistry (Moscow), 2011; PMID 22117547) documented its penetration into the cell nucleus and sequence-specific interaction with DNA in HeLa cell culture. For Research Use Only.

Description
About this peptide
About This Compound
Testagen (Lys-Glu-Asp-Gly) is a short synthetic peptide belonging to a family of tetrapeptide bioregulators derived from tissue-specific amino acid composition studies. It has been examined in cell-culture and animal-model research for its capacity to enter the cell nucleus and interact with defined DNA sequence motifs, as well as for its activity within the pituitary-thyroid axis following hypophysectomy in avian models. The way a key is cut to fit one specific lock, Testagen and related short peptides are studied for sequence-specific binding to particular regions of genomic DNA.
Research Context
Fedoreyeva et al. (Biochemistry (Moscow), 2011; PMID 22117547) documented Testagen's penetration into the nucleus of HeLa cells and its sequence-specific interaction with deoxyribooligonucleotides, noting a binding preference for CAG-containing DNA sequences. Kuznik et al. (Bulletin of Experimental Biology and Medicine, 2008; PMID 19024016) studied Testagen alongside a related tetrapeptide in neonatally hypophysectomized chickens, documenting changes in thyrotropic and thyroid hormone concentrations and thyroid gland structure over a 40-day observation period. Kuznik et al. (Advances in Gerontology, 2011; PMID 21809626) extended this hypophysectomized bird model to mature and old animals, comparing thyroid morphology and hormonal activity outcomes across age groups.

Orders ship within 24 hours. Delivered via USPS Priority or standard FedEx unless expedited shipping is selected at checkout. Tracking is emailed on dispatch and mirrored in your account.
In-transit handling
Lyophilized vials are shelf-stable and ship at ambient temperature. Storage in our warehouse is cooled; shipment does not require refrigeration.
Long-term storage
Lyophilized vials are shelf-stable at ambient temperature; refrigeration (2–8°C) extends shelf life. Refer to the batch-specific Certificate of Analysis for material-specific storage guidance. Once reconstituted, follow the storage instructions on the batch COA. Not for human or animal consumption.
Returns
Because these are research-grade biologics, we cannot accept returns on opened vials. Damaged-in-transit shipments are replaced at no cost within 7 days of delivery.
