Our lots are synthesized under ISO-audited facilities, purified by reverse-phase HPLC, and verified by mass spectrometry. Each unit ships with a unique Certificate of Analysis and a tamper-evident seal so your data starts with integrity.

Yes. After final filtration through a 0.22-micron membrane, lyophilized powder is endotoxin-tested to assure levels below 0.25 EU mg. That keeps cell cultures clean and results reproducible.

Keep unopened vials at −20 °C in a light-protected container. Once reconstituted, aliquot and freeze at −80 °C to minimize freeze–thaw cycles. Room-temperature exposure beyond eight hours invites degradation.

No. They are not drugs, foods, or dietary supplements. They are strictly for laboratory research. Any mention of ingestion, injection, or diagnostic application voids our warranty and breaches the purchase agreement.

Wear gloves, eye protection, and a lab coat. Work inside a Class II biosafety cabinet if your assay involves cell culture. Dispose of unused material according to your institutional chemical-waste protocol.

Every lot is screened for arsenic, cadmium, lead, and mercury using ICP-MS, and for bacterial or fungal growth via USP <61> methods. Results appear on the Certificate of Analysis.

Parallel or sequential administration is at the investigator’s discretion. Validate compatibility by running individual controls first, then document interaction effects on your chosen endpoints.

We replace vials that arrive broken, contaminated, or outside temperature specifications when notified within forty-eight hours of delivery and accompanied by photographic evidence. Because these materials are perishable research reagents, we cannot accept returns.
