Certificate of Analysis

Certificate of Origin

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Why choose Product D1556, OptiPrep, instead of other density gradients such as Percoll or Histopaque?

    Percoll and Histopaque must be removed prior to use through washing.  If Percoll and Histopaque are not removed, these density gradients can be toxic to mammalian cells.  In comparison, OptiPrep has no potential for bioaccumulation and can be considered nontoxic to cells. OptiPrep also has lower viscosity as compared to polysucrose based products such as Histopaque or Ficoll.

  4. What is the appearance of Product D1556, OptiPrep?

    The solution may be clear to slightly yellow.

  5. How do I find price and availability?
