    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. What is MU and how does this relate to milligrams?

      MU is million units. You can convert this to mg by dividing package size by the unit activity listed on the Certificate of Analysis for your specific lot.

    4. What is the solution stability of Product P0972, Polymyxin B sulfate?

      For solution stability information, please refer to the product information sheet for a related Polymyxin B sulfate product (Product No. P1004).

    5. I see that you list several Polymyxin B Sulfate products (P0972, P1004, P4932, 81334 and P4119). What are the differences?

      The primary difference between the products is the testing. Product P0972 is USP tested, product P4932 is tested against 3 mammalian cell lines to make sure it is not toxic to the cells, product P4119 is cell culture and endotoxin tested, and products P1004 and 81334 are the research grades with P1004 in USP units and 81334 in international units.
