Testagen Research Peptide

Testagen (KEDG) is a synthetic tetrapeptide of the Khavinson bioregulator family, examined in the research literature as a testis-directed short-peptide probe for studying tissue-specific gene-expression regulation in reproductive-tissue experimental systems.

Within the Khavinson framework, short peptides of this class are proposed to act at the chromatin/transcriptional level; Testagen is used as a tool compound for peptide-driven regulation studies and as a comparator in tissue-specificity panels across the bioregulator family.

Our Testagen is independently verified to ≥99% purity by HPLC and MS, and ships with a batch-specific Certificate of Analysis.
