Method for identifying modulators of sulfotransferase activity

摘要

The instant invention provides methods for identifying agents that modulate an enzymatic activity of a carbohydrate sulfotransferase. The methods generally involve contacting the sulfotransferase, in a reaction solution, with a sulfate donor, a test agent, and a polymeric sulfate acceptor that is readily separated from the reaction solution. Determination of an effect of the test agent on the sulfotransferase is by detecting the amount of sulfate in the polymeric sulfate acceptor that has been separated from the reaction solution. The invention further provides kits for use in carrying out the subject methods.
