  3. What is the meaning of "type XX" in R1753?

    1 answer
    1. There are three classes of RNA: Messenger, Ribosomal, and Transfer. The type designations on products offered by Sigma are in-house designations and do not represent any specific biochemical significance. These designations can refer to the order of addition of the product to the catalog, source of material, method of preparation, differences in specifications, and so on.

  7. How many mgs of tRNA, Product R1753, come in the 100UN, 500UN, 2KU and 10KU package sizes?

    1 answer
    1. The amount of powder will vary between lots depending on the activity.  For example, a Certificate of Analysis of a lot may say 18 A260 units/mg solid.  This means that the 100UN package will contain approxomately 5.56 mg of solid.
