Reviews from Canadian researchers.

"The COA archive is the differentiator. We can cross-reference any lot we have used historically against the same Janoshik chromatogram."

"Cold-chain packaging arrived still cold after a 48-hour transit to our Halifax bench. Quality is reproducible across lots."

"Mass spec confirmation matched the published value to 0.1 Da. Endotoxin under our 0.1 EU/mg threshold every time."

"Third order in two years. Lumera's HPLC purity floor is the only thing keeping me from switching back to a US supplier."

"Lot-retain archive saved us once when our assay drifted — Lumera ran their retain against ours and pinpointed our reagent issue."

"Janoshik retest matched their numbers. We paired this with our previous reference standard and saw consistent activity."

"Reconstitution was clean. Lyophilized vials sealed under nitrogen — no degradation evident on receipt at our Saskatoon lab."

"As a Quebec researcher, the bilingual customer service is appreciated. Detailed answers within hours, not days."

"Lumera's transparency on every lot — purity, mass, endotoxin, signed Janoshik certificate — is what reproducibility actually requires."

"The stack-builder is brilliant for protocol design. We've cut catalog-search time by 75%."
