[Monoclonal antibody-based immunoenzyme test system for determining the total immunoglobulin E level of children and...

Enzyme immunoassay for determination of total immunoglobulin E in children and adolescents based on combination of two monoclonal antibodies with high affinity and specificity to different epitopes of IgE molecule has been developed. Monoclonal antibodies IgE/11-4 are used for sensitization of a solid phase (96-well plate), mcAB IgE/11-1 conjugated with horseradish peroxidase are used as a developing reagent. The following analytical characteristics of a test-system are established: range of assay--1-100 IU/ml sensitivity--1 IU/ml; time of analysis--1.5 hour, sample volume in duplicates--30 microliters. Immunoassay is simple, reliable and can be used in the field of pediatrics and allergology.
