  • Method and reagent system for assaying isoenzyme profiles
    Patent number: 5364765
    Abstract: The present invention discloses a rapid assay method for quantitatively determining the complete isoenzyme profile of a biological fluid and a multiple-assay reagent system for carrying out the method. In one preferred embodiment, a multiple-assay reagent system is disclosed for quantifying the complete isoenzyme profile of lactate dehydrogenase in blood serum, based on two measured parameters and three performed assays.

  • Method and reagent for determining LD-1 isoenzyme
    Patent number: 5158873
    Abstract: A rapid and specific method and reagent for determining LD-1 isoenzyme in biological fluids by incorporating a chaotropic agent, such as sodium perchlorate, into an LDH assay reagent system. The chaotropic agent produces an immediate inactivation of the LDH isoenzymes containing one or more `M` type subunits while the LTD-1 isoenzyme remains stable and is simultaneously measured.
