Compound Type
Polynucleotide
Last updated
A chain of nucleotides, the building blocks of DNA, usually purified from a biological source and cut to a defined range of fragment lengths. Two labels appear commercially: PDRN, meaning polydeoxyribonucleotide, and PN, meaning polynucleotide, which are generally described as differing in fragment length. These contain no amino acids and are not peptides in any sense.
Flagged for specialist review
This entry describes something contested, or asserts a detail we have not been able to confirm against a settled source. It is published rather than withheld, with the flag visible, because an entry you can weigh beats a gap you cannot see.
Why it matters here
A polynucleotide product is a mixture spanning a length range rather than one defined molecule, so its batch documentation describes a distribution, and two products carrying the same name are not necessarily the same material.
What it is not
PDRN and PN are used interchangeably in marketing and are not identical; the stated difference is fragment size, and suppliers vary in where they draw it. These are also routinely sold under the word peptide while sharing no chemistry with one, the starting material typically being salmon DNA.
Also called
- polynucleotide
- pdrn
- pn
- dna fragment
PDRN stands for polydeoxyribonucleotide and PN for polynucleotide. Both appear on labels, often on products described as the same thing.
