In research settings, this peptide is commonly utilized for studying testicular cell signaling, hormone-related transcription factor activity, and related biochemical mechanisms.\u003c\/p\u003e\n\u003cp\u003eTestagen is a Khavinson-class short-peptide bioregulator with the sequence L-Lys-L-Glu-L-Asp-L-Gly (KEDG), originally derived from analysis of testicular tissue extracts by Prof. Vladimir Khavinson's research group. Short peptides in this class are hypothesized to interact with DNA in a sequence-specific manner, modulating gene expression within their tissue of origin. Testagen shares three of four residues with Livagen, substituting glycine for alanine at the C-terminus, which is associated with testicular-tissue specificity within the Khavinson framework.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003eSequence: L-Lys-L-Glu-L-Asp-L-Gly (KEDG)\u003cbr\u003e\nMolecular Formula: C₁₇H₂₉N₅O₉\u003cbr\u003e\nMolecular Weight: ~447 g\/mol\u003cbr\u003e\nPurity: ≥ 99%\u003cbr\u003e\nCAS: 1026993-38-3\u003cbr\u003e\nForm: Lyophilized powder\u003c\/p\u003e\n\u003ch3\u003eResearch Use Only\u003c\/h3\u003e\n\u003cp\u003eThis product is intended for laboratory research purposes only and is not for human or veterinary use, diagnostic procedures, or therapeutic application.\u003c\/p\u003e","brand":"American Peptides","offers":[{"title":"20 mg","offer_id":48630176383131,"sku":"TST-20","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/2876\/6619\/files\/download_cfb1679e-f529-4d2d-8fa7-a3e4bf360d06.png?v=1779568901","url":"https:\/\/www.americanpeptides.us\/products\/testagen","provider":"American Peptides","version":"1.0","type":"link"}
