  • Publication number: 20160101054
    Abstract: Biodegradable polymeric microparticle compositions containing one or more active agents, especially those useful for treating or preventing or one or more diseases or disorders of the eye, and methods of making and using thereof, are described. The microsphere compositions release an effective amount of the one or more active agents for a period greater than 14 days in vivo, preferably greater than 60 days in vivo, more preferably up to 73 days in vivo, more preferably greater than 90 days in vivo, even more preferably over 100 days in vivo, and most preferably greater than 107 days in vivo. In a preferred embodiment, the microparticle compositions contain one or more active agents such as AG1478 to induce nerve regeneration, specifically regeneration of the optic nerve useful for managing elevated intraocular pressure (IOP) in the eye.

  • Patent number: 4478744
    Abstract: Antibodies specific to glycosylated hemoglobin and substantially free of cross-reactivity with nonglycosylated forms of hemoglobin are obtained by administering a synthetic antigen to a host animal. The antigen comprises a glycosylated synthetic peptide having an amino acid sequence corresponding to that of the NH.sub.2 -terminus of the .beta.-chain of hemoglobin. The peptide comprises a sequence of between about four and ten, and preferably seven, amino acids, and is conjugated with glucose and a protein. The protein preferably comprises an immunoglobulin which is foreign to the host animal.

  • Patent number: 4465774
    Abstract: A control material for use in the determination of glycosylated and total hemoglobin, and a method of preparing the same, are disclosed. The control is prepared by the steps of hemolyzing red blood cells, preferably in the presence of a detergent, followed by removal of stroma and lipids from the hemoglobin with an organic solvent such as toluene in the presence of a polyhydroxy compound such as sucrose. A hemoglobin-rich fraction is separated from the resulting mixture and dialyzed against a solution of a polyhydroxy compound. The dialysate may be lyophilized to provide a stable, dry product suitable for reconstitution.
