    Type: Grant
    Filed: February 16, 1996
    Date of Patent: June 9, 1998
    Assignee: The Liposome Company, Inc.
    Inventors: Eric Mayhew, Andrew S. Janoff, Imran Ahmad, Suresh K. Bhatia
  • Patent number: 5662930
    Abstract: Provided herein is a method of administering a liposome composition to an animal, the method involving adminstering to the animal a liposome composition containing an adverse physiological reaction-reducing effective amount of a liposome which has, in addition to a bioactive agent, a lipid bilayer containing a lipid and a surface agent-modified molecule. An adverse physiological reaction which may be experienced by the animal upon administration of a liposome composition is reduced by way of the presence of the surface agent-modified molecule in the liposome's lipid bilayer.
    Type: Grant

  • Patent number: 5077210
    Abstract: Active agents such as proteins are covalently immobilized on substrates carrying hydroxyl groups. A silane is bound to the substrate and coupled to a heterobifunctional crosslinker at one functional group leaving a free functional group, different than the first group, to which a protein is bound while retaining high protein functionality. Preferably, the silane has a functional group which reacts with the hydroxyl group of the substrate and a thiol terminal group which reacts with a functional group of a heterobifunctional crosslinking agent which contains a succinimide group that reacts with an amino group of the active agent. Bound active agents such as proteins are useful as biosensors or reactants in a variety of applications including bioassays.
