Quality and handling
Sourcing, testing, and the cold chain, described plainly.
Testing
Every batch is tested by an independent laboratory before release. We report the assay as the lab issues it, including the lot number it applies to. We do not average results across lots, and we do not publish a figure for a batch that has not been tested.
Two things get measured: purity by HPLC, and identity by mass spectrometry. Purity without identity is incomplete, because it tells you the sample is clean without telling you what it is.
Sourcing
Compounds are sourced from synthesis partners who supply a batch record with the material. Where a supplier cannot provide traceable batch documentation, we do not list the compound. This is the reason our catalogue is short.
Storage and handling
Lyophilised peptides are held at -20 °C for long term storage. In this form they tolerate ambient transit, which is why shipping does not require a cold pack for most compounds. Light sensitive material, such as copper complexes, is stored and shipped protected from light.
Once a vial is reconstituted the requirements change. Solutions are refrigerated, protected from light, and dated against the lot number.
Packaging
Vials ship sealed, cushioned against impact, in packaging that does not describe the contents on the outside. The batch record travels with the order.
Chain of custody
Each order records the lot shipped against the order number. If a question comes up later, we can tell you exactly which batch you received and hand you the certificate for it.
What we do not claim
Vantra holds no pharmaceutical manufacturing licence and makes no such claim. These are research chemicals supplied for in vitro laboratory work. They are not evaluated by Health Canada, they are not therapeutic products, and they are not for human or animal consumption.
