  • Patent number: 7790447
    Abstract: An object of the present invention is to provide an expression vector that allows for stable production of N-deacetylase/N-sulfotransferase 2 in large amounts and a process for production of N-deacetylase/N-sulfotransferase 2 using the same. The present invention provides a recombinant baculovirus expression vector obtained by incorporating into baculovirus DNA, a DNA fragment having lobster L21 DNA, DNA encoding gp67 signal peptide and DNA encoding the 79th to 883rd amino acids of human N-deacetylase/N-sulfotransferase 2 in this order in the 5? to 3? direction.
    Type: Grant
    Filed: July 27, 2005
    Date of Patent: September 7, 2010
