Why ≥95% by SDS-PAGE is stated per lot
Purity is reported as ≥95% by SDS-PAGE, with the figure paired to that method on the certificate of analysis. The certificate is lot-specific, so the vial in hand can be matched to its own document. Purchasing officers who need documentation on file can download it per lot.
How to store the lyophilized 1 mg vial
Store the lyophilized protein sealed at -20 °C or below, protected from light. Repeated freeze–thaw should be avoided once the protein is reconstituted for in-vitro work. No other consumables are included with the vial.
Who the single 1 mg vial suits
The unit is a single vial containing 1 mg of protein, ordered by laboratories and qualified researchers. Shipping is from Richmond, BC in an insulated mailer with desiccant. Packed weight for the courier is 0.05 kg; the net content is the 1 mg stated in the name.
Common questions
Is a certificate of analysis included with the vial?
Yes. A lot-specific certificate of analysis is available for download, stating purity as ≥95% by SDS-PAGE.
How should the vial be stored after it arrives?
Store the lyophilized protein sealed at -20 °C or below and protected from light, and avoid repeated freeze–thaw once reconstituted.
Where does the order ship from, and how is it packed?
Orders ship from Richmond, BC in an insulated mailer with desiccant, and the material is sold for research use only to laboratories and qualified researchers.
