IgE ELISA kits
We make ELISA kits for IgE in 2 species. This page explains how they differ, so you can pick the one your experiment needs.
What differs between these kits
Which species they are for
Available for Human and Mouse. The species decides which antibody pair we supply, so it is the first thing to choose. Some kits are also validated on closely related species, so if you work in one we do not list here, check the reactivity on the product page.
Whether a pre-coated plate is included
Some of our kits arrive with the plate already coated with the capture antibody, so you can start with your samples. Others supply the antibodies and standard only. Coating your own plate is more work, and it gives you control over the coating conditions and the plate.
Which detection system
Available with Streptavidin-ALP or Streptavidin-HRP. You add the streptavidin conjugate as a second incubation after the biotinylated antibody, which amplifies the signal. Alkaline phosphatase (ALP) and horseradish peroxidase (HRP) perform equivalently, so that choice usually comes down to the substrate and reader you already work with.
About IgE
The main physiological function of immunoglobulin E (IgE) is to protect against parasitic infestation. However, IgE is also associated with allergy, and allergen-specific IgE antibodies may trigger allergic reactions in the presence of the allergen. IgE is normally found in low amounts in serum/plasma but is significantly increased in allergic individuals, and the detection of allergen-specific IgE serves as the basis for many in vitro assays for allergy diagnosis.
