  • Method for determination of allergen in environment and kit for simple quantification of allergen
    Patent number: 8012708
    Abstract: A simple method for measuring allergens is disclosed, by which the amount of environmental allergens can be measured simply without using an anti-allergen antibody. In the method for measuring an environmental biological allergen(s), a solution containing a substrate of a protease which the allergen(s) has (have) is brought into contact with a test sample collected by using an adhesive sheet, which substrate gives a visible color change as a result of an enzyme reaction; and measuring the protease activity in the test sample using the color change of the substrate solution as an index, thereby measuring the biological allergen(s).
