Documentation, Not Marketing Figures
Why Janera leads with the data.
Janera Science is built around testing transparency and documentation. Each lot is tested by an independent laboratory before release, for HPLC purity and assay, heavy metals by ICP-MS, endotoxin by LAL and sterility by USP <71>.
For researchers, purity is not a marketing figure but the difference between reproducible data and experimental noise. A purity percentage on its own can mislead, since HPLC purity is not the same as net peptide content, so Janera presents the figure alongside the method and the batch documentation.
The aim is to remove uncertainty, so purity, method, and lot can be evaluated together before a compound enters your work.
How The Purity of Research Peptides is Verified
HPLC purity analysis
HPLC reports the purity percentage by separating the target peptide from synthesis by-products.
Heavy metal, endotoxin and sterility testing
Each posted certificate also reports ICP-MS results for arsenic, cadmium, lead and mercury, LAL endotoxin and USP <71> sterility.
Batch-specific certificate of analysis
A batch-specific certificate of analysis records the results, tied to the lot you receive. Certificates are on the lab results page.
What Every Order of High-Purity Peptides Includes
Batch-specific certificate of analysis
Each posted certificate of analysis is tied to a production lot and reports HPLC purity and assay, heavy metals, endotoxin and sterility.
Lyophilized for stability
Compounds are supplied as lyophilized powder. Freeze-drying removes the water that drives the most common forms of peptide degradation.
Full chemical documentation
Each product lists molecular formula, molecular weight, CAS number, and sequence, so the material can be matched to laboratory records.
