Catalog / Anti-IgE antibodies
Anti-IgE antibodies
We make 7 antibodies against IgE for 2 species, unconjugated or conjugated to biotin. This page explains how they differ, so you can pick the one your experiment needs.
Rather use a ready-made kit? See our IgE ELISA kits, IgE ELISpot kits, IgEa ELISA kits, and IgEa ELISpot kits.
What differs between these antibodies
Which species they are for
Available for Human and Mouse. This is the species whose immunoglobulin you want to detect, and it decides which clones there are, so it is the first thing to choose.
Which clone
We make 6 anti-IgE antibody clones. A clone is one specific antibody that binds one site on its target, so it is what you cite or reorder by name. A sandwich assay needs two clones that bind different sites; the capture and detection pairs below are matched for that.
Which conjugate
Unconjugated antibodies carry no label. You coat a plate with them as the capture antibody, or use them where the antibody itself is the reagent. Biotinylated antibodies are detected with a streptavidin conjugate, such as streptavidin-ALP or streptavidin-HRP.
Capture and detection pairs
To build your own IgE ELISA or ELISpot, coat with the unconjugated capture antibody and detect with the biotinylated detection antibody, then a streptavidin conjugate. These are the same pairs our own kits use.
| Species | Capture | Detection | For |
|---|---|---|---|
| HumanELISA | 107 | 182, biotin | ELISA |
| MouseELISA, ELISpot | MT56E | MT44E, biotin | ELISA, ELISpot |
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.
