  • Helicobacter pylori antigens in blood
    Patent number: 6794153
    Abstract: The present invention relates to the finding and detection of Helicobacter pylori (H. pylori) antigens in blood of infected individuals. The H. pylori antigens are components of H. pylori cells which include, but not limited to DNA, RNA, and fragments of nucleotides, proteins or peptides. H. pylori DNA, RNA, and fragments of nucleotides can be detected by polymerase chain reaction (PCR), ligase chain reaction (LCR), or DNA hybridization methods or other amplification methods. H. pylori proteins or peptides or other antigenic components thereof can be detected by immunoassays or immunoblot using an antibody against H. pylori, preferably an antibody purified by an affinity column. The present invention further provides immunoassay methods, diagnostic kits, and an immunochromatographic assay device for detection of Helicobacter pylori antigens in serum samples.

  • Peptides for the diagnosis of HTLV-III antibodies, their preparation and use
    Patent number: 4753873
    Abstract: Certain peptide fragments of the human T-cell leukemia (lymphotropic) virus (HTLV-III) are particularly immunoreactive to HTLV-III antibodies, and can therefore be applied to immunodiagnostic tests for the detection of antibodies to HTLV-III.

  • Process for purifying recombinant proteins, and products thereof
    Patent number: 4734362
    Abstract: The present invention relates to a process for recovering recombinant protein from refractile inclusion bodies of microorganisms which comprise disrupting cells, recovering refractile bodies containing recombinant protein, solubilizing the refractile bodies with a denaturant, protecting sulfhydryl groups of recombinant proteins, converting cationic amino groups of recombinant proteins to anionic carboxylic acid by derivatization with organic cyclic acid anhydrides, and recovering recombinant protein derivatives.The present invention also relates to the production of solid supports coated with recombinant protein recovered by the process of the invention, and the use of said devices for the detection and quantification of antibodies to said recombinant proteins in body fluids.
