Salmon, commonly known as salmon or sockeye, is a cold-water migratory fish with high nutritional value. It is a delicacy on the dining table whether consumed raw or cooked. In addition to the commonly consumed flesh and roe, the salmon milt, also known as fish white, contains a variety of amino acids and rare nucleic acid components such as DNA-Na.

DNA-Na, also known as PDRN (Polydeoxyribonucleotide), is a mixture of polymeric deoxyribonucleotides and serves as one of the raw materials for DNA synthesis within cells. It is applied in various fields such as regenerative medicine, cosmetics, and functional foods.
