  5. Can Product C100, Catalase from bovine liver, be shipped on wet ice or dry ice?

    Product No. C100 normally ships at ambient temperature. If desired, it can be shipped on wet ice upon special request. C100 cannot be shipped on dry ice. That is, the suspension can be harmed by freezing.

  6. Is Product C100, Catalase from bovine liver, a solution or a suspension?

    Most of the protein (catalase) in Product No. C100 is a solid in suspension, with a small percentage actually in solution.

  7. Is Product C100, Catalase from bovine liver, sterile?

    C100 is not necessarily sterile. But it does contain a preservative (0.1% thymol), which should prevent microbial growth.

  8. What is the catalase concentration of Product C100, Catalase from bovine liver?

    There is no "official" specification, but the lot history shows that it has varied from 15-100 mg/mL. The concentration is provided on the certificate of analysis for each lot. Note that most of the catalase is typically a solid in suspension, with a small percentage actually in solution.

  9. Your website shows that Product No. C100 is catalase. But I have some notes that indicate that C100 is your product number for calmidazolium chloride. Which one is right?

    C-100 was used as a product number for calmidazolium chloride until about 1999 by Research Biochemicals International (RBI), which is now part of Sigma-Aldrich. Calmidazolium chloride is currently listed under Sigma Product No. C3930. So now we use the C100 only for catalase.
