  • Method for cloning and producing the SFII restriction endonuclease and methylase
    Patent number: 5637476
    Abstract: The present invention is directed to a method for cloning and producing the SfiI restriction endonuclease by 1) introducing the restriction endonuclease gene from S. fimbriatus into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the plasmid encoding and expressing the SfiI restriction endonuclease activity; and 3) purifying the SfiI restriction endonuclease from the fermented host which contains the plasmid encoding and expressing the SfiI restriction endonuclease activity.
    Type: Grant
    Filed: April 21, 1993
    Date of Patent: June 10, 1997
    Assignee: New England Biolabs, Inc.
    Inventor: Elizabeth M. Van Cott
  • Method for cloning and producing the NaeI restriction endonuclease and methylase
    Patent number: 5292651
    Abstract: The present invention is directed to a method for cloning and producing the NaeI restriction endonuclease by 1) introducing the restriction endonuclease gene from Nocardia aerocolonigenes into a host whereby the restriction gene is expressed; 2) fermenting the host which contains the plasmid encoding and expressing the NaeI restriction endonuclease activity, and 3) purifying the NaeI restriction endonuclease from the fermented host which contains the plasmid encoding and expressing the NaeI restriction endonuclease activity.
    Type: Grant
    Filed: May 12, 1992
    Date of Patent: March 8, 1994
    Assignee: New England Biolabs, Inc.
    Inventors: Ellen P. Guthrie, Elizabeth M. Van Cott, Christopher H. Taron
  • Method for producing the FnuDI restriction endonuclease and methylase
    Patent number: 4988620
    Abstract: The present invention is directed to a method for cloning and producing the FnuDI restriction endonuclease by (1) introducing the restriction endonuclease gene from F. nucleatum D into a host whereby the restriction gene is expressed; (2) fermenting the host which contains the vector encoding and expressing the FnuDI restriction endonuclease, and (3) purifying the FnuDI restriction endonuclease from the fermented host which contains the vector encoding and expressing the FnuDI restriction endonuclease activity.
    Type: Grant
    Filed: December 17, 1987
    Date of Patent: January 29, 1991
    Assignee: New England Biolabs, Inc.
    Inventors: Elizabeth M. Van Cott, Geoffrey G. Wilson
  • Method for producing the XbaI restriction endonuclease and methylase
    Patent number: 4983542
    Abstract: The present invention is directed to a method for cloning and producing the XbaI restriction endonuclease by (1) introducing the restriction endonuclease gene from Xanthomonas badrii into a host whereby the restriction gene is expressed; (2) fermenting the host which contains the vector encoding and expressing the XbaI restriction endonuclease, and (3) purifying the XbaI restriction endonuclease from the fermented host which contains the vector encoding and expressing the XbaI restriction endonuclease activity.
