Patents by Inventor Michael Edlund

Michael Edlund has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nucleic acids encoding BSSL variants
    Patent number: 5827683
    Abstract: The invention discloses nucleic acids encoding variant Bile Salt Stimulated Lipase (BSSL; EC 3.1.1.1). The encoded variant BSSL enzymes maintain catalytic activity but contain fewer glycosylation sites that full-length BSSL. This reduced glycosylation facilitates purification and characterization of recombinant BSSL proteins.
    Type: Grant

  • Transgenic non-human mammals producing BSSL variants
    Patent number: 5763739
    Abstract: The present invention relates to novel polypeptides which are variants of Bile Salt-Stimulated Lipase (BSSL; EC 3.1.1.1). It also relates to DNA molecules encoding the said polypeptides, and to subproducts comprising the said DNA molecules. The invention further relates to processes for producing the said BSSL variants and for producing transgenic non-human mammals capable of expressing the BSSL variants.Furthermore the invention relates to such transgenic animals as well as to infant formulas comprising milk from such transgenic animals. The invention also relates to pharmaceutical compositions comprising the said polypeptides; and the use of the said polypeptides and DNA molecules for the manufacture of medicaments.
