The DIA HE1 IgE is an affinity-purified, fully human IgE antibody with
kappa light chains. It is produced in vitro from a monoclonal hybridoma. This unique
source guarantees freedom from contamination by other immunoglobulin isotypes.
Compared to IgE from a myeloma patient, where batch-to-batch variability may
be high, the monoclonal source of IgE ensures very high reproducibility.
This human IgE is used widely in the field of allergy research and diagnostic kit
manufacturing, mostly as a standard in quantitative IgE assays and for internal
control and QC purposes.
