Polydeoxyribonucleotide (PDRN) is primarily extracted from natural DNA sources of fish, especially species rich in sperm DNA.
Main Source (Primary Industry Source)
1. Salmon and Trout Sperm DNA
The most common and commercially used source is:
- Salmon (Oncorhynchus keta)
- Rainbow trout (Oncorhynchus mykiss)
Polydeoxyribonucleotide (PDRN) is extracted specifically from:
- Sperm cells (milt) of fish
- Not from muscle or edible tissue
Why sperm DNA?
- Very high DNA concentration
- Relatively pure nuclear material
- Easy large-scale extraction
- Low contamination with proteins and lipids
Raw Material Origin
The biological material comes from:
- Fish hatcheries and aquaculture industries
- Controlled breeding populations
- Processed by pharmaceutical-grade extraction facilities
The sperm is collected and then the DNA is purified and fragmented into Polydeoxyribonucleotide (PDRN).
Extraction Process Overview
While methods vary slightly by manufacturer, the general process includes:
1. Collection
- Fish sperm (milt) is harvested
2. Cell lysis
- Cell membranes are broken to release DNA
3. DNA purification
Removal of:
- Proteins
- Lipids
- RNA
- Cellular debris
4. Fragmentation
- DNA is enzymatically or physically cut into short double-stranded fragments
5. Sterilization & purification
- Filtration and purification to medical-grade standards
6. Final product
- Polydeoxyribonucleotide (PDRN) solution or lyophilized powder
Alternative / Minor Sources
Less common or experimental sources include:
- Other marine organisms (limited use)
- Plant-derived nucleotides (not true Polydeoxyribonucleotide (PDRN), usually polynucleotide mixtures)
- Synthetic DNA fragments (research stage only)
However, clinical-grade Polydeoxyribonucleotide (PDRN) is almost always salmon or trout-derived.
Why fish DNA is used (important reason)
Fish sperm DNA is preferWhy fish DNA is used (important reason)red because:
- High yield per biomass
- Evolutionarily conserved nucleotides (compatible across species)
- Low risk of prion or mammalian pathogen contamination
- Stable and easy to purify at scale
Key Summary
- Main source: Salmon and trout sperm (milt)
- Material extracted: Nuclear DNA
- Processed into: Short DNA fragments (Polydeoxyribonucleotide (PDRN))
- Used for: Regenerative medicine and dermatology
- Why fish: High purity, safety, and industrial scalability
If you want, I can also explain how Polydeoxyribonucleotide (PDRN) differs depending on extraction method (enzymatic vs thermal hydrolysis) or why its source affects biological activity in skin repair.
