ABSTRACT:
The present invention provides a one-step process for the detection of the presence of an allergy and for the specific detection of the allergen responsible for the allergy, in which the leukocytes of a sample to be investigated are incubated with an allergen or with another stimulation factor in an aqueous medium together with a chromogenic protease substrate and calcium ions, the liberated protease is reacted with the chromogen and the resulting chromophor is determined. The protease activity is measured kinetically after an incubation period by the increase of the chromophor concentration. The present invention also provides a reagent and a device for carrying out this process, as well as a process for the determination of antiallergic and anti-inflammatory substances. The device consists of a microtiter plate with a plurality of different reagents arranged in rows.
