  • Methods for detection, determination, and activity measurement of peroxidase based on chemiluminescence
    Patent number: 11879148
    Abstract: A further high-sensitive method for detection, determination, and activity measurement of peroxidase with no special enhancer argent. The substance, for example, high-concentration ammonium sulfate, is dissolved in the reaction solution to give rise to the micro-hydrophobic property, for detection, determination, and activity measurement of peroxidase using luminol and hydrogen peroxide as substrates.
    Type: Grant

  • Immobilization of peptide-containing compounds on metal hydroxide gels
    Patent number: 4897468
    Abstract: Peptide-containing compounds such as enzymes, antibodies and antigens are immobilized on metal hydroxy gels formed by hydrolysis of metal alkoxides in an aqueous solvent while evaporating off the solvent. Preferably, hydrogen fluoride is present in the solvent during hydrolysis to provide a fluoride-substituted metal hydroxy gel. Water containing lower alcohol is a preferred solvent. The gel is treated with a coupling agent and a peptide-containing compound is chemically bonded to the gel.
