Each vial holds 1 mg of recombinant follistatin protein, expressed and purified for in-vitro work. Purity is ≥95% by SDS-PAGE, and a lot-specific certificate of analysis is available for download. The protein is supplied lyophilized and sold for research use only.
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.
