  • Purified ciliary neurotrophic factor
    Patent number: 5780600
    Abstract: A ciliary neurotrophic factor (CNTF), particularly sciatic nerve CNTF (SN-CNTF) is claimed. The SN-CNTF described herein is a single protein species and has a specific activity that increased to greater than 25,000-fold from crude extract. Amino acid data for this SN-CNTF is also provided. In addition, methods for using this data for providing SN-CNTF probes and for screening cDNA and genomic libraries are also provided. Recombinant-DNA methods for the production of SN-CNTF are described. Nucleic acid sequences encoding rabbit and human CNTF are provided. A recombinant expression system is provided for producing biologically active CNTF.
    Type: Grant
    Filed: May 24, 1995
    Date of Patent: July 14, 1998
    Assignee: Amgen Inc.
    Inventors: Franklin D. Collins, Leu-Fen Lin, Drzislav Mismer, Christine Ko
  • DNA encoding 85kd polypeptide useful in diagnosis of Mycoplasma infections in animals
    Patent number: 5459048
    Abstract: A class of polypeptides useful in an in vitro diagnosis of Mycoplasma infection in animals is disclosed. These polypeptides are also capable of inducing an immune response in swine which were previously not exposed to Mycoplasma. Recombinant DNA methods for the production of these polypeptides and certain phage vectors and DNA sequences useful in these methods are also disclosed. Methods of vaccinating animals utilizing a vaccination composition which includes these polypeptides is also disclosed.
    Type: Grant
