BASICS
What are peptides?
A short guide to understand what we are talking about — without unnecessary jargon — before choosing a reference or reading a product sheet.
- 1
In one sentence
A peptide is a short chain of amino acids — the same “building blocks” that make up proteins, but shorter. In research, they are studied to understand specific biological signals.
- 2
Peptide vs protein
Beyond a certain length, we usually speak of a protein. Research peptides are often small synthetic fragments, chosen for a given mechanism or experimental model (tissue, metabolic, neurological, and so on).
- 3
Why lyophilized?
As a lyophilized powder, a peptide stores and ships more easily. In the lab, it is then reconstituted (often with bacteriostatic water) according to the study protocol.
- 4
Purity and COA
Purity (often measured by HPLC) and the certificate of analysis (COA) document what a lot contains. At SanaPept, every reference is selected for research with a strong traceability requirement.

Strictly research use
The peptides on this site are intended for laboratory use and regulated experimentation only. They are not medicines and are not for human or animal consumption.
