Publication number: 20080058246Abstract: Methods are provided for the synthesis of polymer conjugates of cytokines, chemokines, growth factors, polypeptide hormones and receptor-binding antagonists thereof, which conjugates retain unusually high receptor-binding activity. Preparation of polymer conjugates according to the methods of the present invention diminishes or avoids steric inhibition of receptor-ligand interactions that commonly results from the attachment of polymers to receptor-binding regions of cytokines, chemokines, growth factors and polypeptide hormones, as well as to agonistic and antagonistic analogs thereof. The invention also provides conjugates and compositions produced by such methods. The conjugates of the present invention retain a higher level of receptor-binding activity than those produced by traditional polymer coupling methods that are not targeted to avoid receptor-binding domains of cytokines, chemokines, growth factors and polypeptide hormones.Type: ApplicationFiled: March 27, 2007Publication date: March 6, 2008Applicant: Mountain View Pharmaceuticals, Inc.Inventors: Shyam Bhaskaran, Merry Sherman, Mark Saifer, L.

Patent number: 7054061Abstract: A split-band amplifying apparatus that has a first section for amplifying a long wavelength band of an optical signal and a second section equipped with a fiber amplifier for amplifying a short wavelength band of the optical signal. The fiber amplifier in the second section uses a short-pass fiber with a depressed cladding cross-section and core doped with an active material, e.g., Erbium, and pumped to a high relative inversion D. The split-band amplifying apparatus can be used to amplify signals whose short wavelength band includes at least a portion of the S-band and whose long wavelength band includes at least a portion of the C- and/or L-band.Type: GrantFiled: January 17, 2003Date of Patent: May 30, 2006Assignee: Lightwave Electronics Mountain ViewInventors: Mark A.

Publication number: 20050014240Abstract: A naturally occurring or recombinant protein, especially a mutein of porcine urate oxidase (uricase), that is essentially free of large aggregates can be rendered substantially non-immunogenic by conjugation with a sufficiently small number of strands of polymer such that the bioactivity of the protein is essentially retained in the conjugate. Such conjugates are unusually well suited for treatment of chronic conditions because they are less likely to induce the formation of antibodies and/or accelerated clearance than are similar conjugates prepared from protein preparations containing traces of large aggregates.Type: ApplicationFiled: August 30, 2004Publication date: January 20, 2005Applicant: Mountain View Pharmaceuticals, Inc.Inventors: Merry Sherman, Mark Saifer, L.
