  • Patent number: 5679536
    Abstract: A chemiluminescent method is provided for the analysis of a target. A peroxidase is first bound as a labelling substance to the target by using a target specific binding reagent. The target so labelled is isolated and then reacted with luminol, hydrogen peroxide and an enhancer in an aqueous solvent. The luminescence of light is detected and measured. The aqueous solvent contains at least one protein selected from the group consisting of skim milk and egg albumin. Preferably, the aqueous solvent also contains a non-ionic surfactant such as a polyoxyethylene ether and/or a sugar alcohol such as mannitol.

  • Patent number: 5534430
    Abstract: The present invention relates to a cell strain capable of separating and multiplying an EB virus and derived from human lymphocyte cancer cells and a method of separating and multiplying the EB virus by means of said cell strain. The present cell strain can be applied to the separation and multiplication of the wild type virus present in various places, as well as to the separation and multiplication of the virus produced by homologous recombination etc. The virus newly separated and multiplied can be applied to vaccine etc. For the more efficient separation and multiplication of the virus, several markers can be inserted into the present cell strain.
