Good quality, competitive price and stable supply.

We could supply food grade PDRN(molecular weight 10,000-20,000Da), cosmetic grade PDRN(molecular weight about 60,000Da),Medical device grade for injection PDRN(molecular weight about 650,000Da) and Medical device grade for injection PN(molecular weight above 1,000,000Da)

Our PDRN extracted from Male salmon sperm. If customers need cheaper PDRN, we also could extract PDRN from other fish.

·Overview

PDRN, also known as Polydeoxyribonucleotide, is a specific DNA fragment extracted from Salmon seminal vesicle, which is one of the components that generate DNA.

The PDRN extracted from Salmon seminal vesicle is 98% similar to human DNA bases.

Introduction and Features

Specifications: ①PN molecular weight ≥1000bp;                        

②PDRN molecular weight ≥500bp and molecular weight ≤200bp.

Purity: ≥99%.

Properties: White powder or fibrous solid

PDRN is derived from Salmon seminal vesicle, and the DNA content of Salmon seminal vesicle is about 7.5% to 15% of its wet weight. The PDRN obtained by us through enzymatic extraction and purification process ensures a very high DNA content,  it does not contain any active proteins and peptides, endotoxin content can meet the injection grade standard.
