Polydeoxyribonucleotide (PDRN) ≥60%

Product Description:
Male fish testes, also known as fish milt, are naturally rich in DNA. Due to their low immunogenicity and high purity, these DNA fragments are widely used in nucleic acid regenerative medicine and serve as the primary raw material for PDRN extraction. This product is derived from salmon testes containing high-purity DNA and is extracted and purified using enzymatic and physical methods. The resulting product consists primarily of low-molecular-weight DNA fragments, with natural PDRN as its core active ingredient.
