What is the meaning of "type XX" in R1753?
1 answer-
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.
