  • Method for recovering and purifying polyglutamic acid
    Publication number: 20050037472
    Abstract: A method for recovering and purifying polyglutamic acid efficiently is disclosed, which method includes the steps of adjusting pH of a solution containing ?-PGA to neutral or slightly acidic range and filtering the solution through a plurality of filtration membranes with various molecular weight cutoffs to recover ?-PGA. Advantages of the method includes using none or minimum of organic solvent, reducing consumption of filtration membranes, reducing water volume for dilution, shortening operation time, high productivity, and obtaining various ?-PGA products with different range of molecular weight.

  • Synthetic peptides for arterial imaging
    Patent number: 5972890
    Abstract: Vascular disease including asymptomatic atherosclerosis can be diagnosed by administering a synthetic peptide or peptide analog having an affinity for, and propensity to accumulate at, a site of vascular injury to a patient, and then detecting the location of the peptide or peptide analog within the patient's vascular system. The synthetic peptide or peptide analog may include an amino acid sequence sufficiently duplicative of the amino acid sequence of a region of either the apolipoprotein B, apolipoprotein A-I, or elastin proteins such that the peptide or peptide analog accumulates at a site of vascular injury.
    Type: Grant
    Filed: February 28, 1995
    Date of Patent: October 26, 1999
    Assignee: New England Deaconess Hospital Corporation
    Inventors: Robert S. Lees, Ann M. Lees, Allan Fischman, Ing-Lung Shih, Mark A. Findeis
  • Synthetic peptides for arterial imaging at vascular imaging sites
    Patent number: 5955055
    Abstract: Vascular disease including asymptomatic atherosclerosis can be diagnosed by administering a synthetic peptide or peptide analog having an affinity for, and propensity to accumulate at, a site of vascular injury to a patient, and then detecting the location of the peptide or peptide analog within the patient's vascular system. The synthetic peptide or peptide analog may include an amino acid sequence sufficiently duplicative of the amino acid sequence of a region of either the apolipoprotein B, apolipoprotein A-I, or elastin proteins such that the peptide or peptide analog accumulates at a site of vascular injury.
