Unit of measure is "mg".
α-2,3-Sialyltransferase is used for in vitro sialylation of all Galβ1-4GlcNAc units on glycoproteins, such as monoclonal antibodies (MABs).
α-2,3-Sialyltransferase is used for targeted, in vitro sialylation of glycoproteins, which are not, or not fully sialylated.
Molar mass: 34.5 kDa by cDNA
A generic protocol for sialylation of glycoproteins is available. However, the optimal conditions depend on different factors (e.g., the initial and target glycosylation status of the glycoprotein) and must be determined by the user.
