Method for the determination of an allergy and method for the specific determination of the allergen responsible for the allergy

摘要

The present invention provides a process for the detection of the presence of an allergy and for the specific detection of the allergen responsible for the allergy, based on the cellular principle, wherein leukocytes of a sample to be investigated are incubated with an allergen or another stimulation factor of degranulation, such as anti-IgE, in an aqueous medium, the leukocytes are then separated off and the remaining solution is incubated with a compound of the general formula: Y-X-C in which Y is an amino acid or a peptide containing 2 or 3 amino acids, the amino acids optionally carrying a conventional protective group on the amino end, X is arginine or lysine and C is a chromogenic residue, in the presence of a buffer effective at pH 6.3 to 8.0 and the liberation of the chromogenic residue is measured.
