  • Methods of oligomerizing olefins
    Patent number: 7638671
    Abstract: The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.
    Type: Grant

  • Method for identifying modulators of sulfotransferase activity
    Patent number: 6713274
    Abstract: 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.
