Immunogen purified human myeloma IgE
Clone Le27-NBS01
Isotype IgG1 kappa
Specificity Human IgE, Fce4, no cross-ractivity with other human or murine Ab isotypes
Purification Affinity - purified from cell culture supernatant by Immunoaffinity Chromatography on CH-Sepharose 4B
Purity > 95 %, tested by analytical Gel Permeation Chromatography
Background The antibody recognizes an epitope within the Ce4 domain of human IgE. It does not block the binding of IgE to its high affinity receptor on mast cells and basophils and is therefore suitable to detect receptor bound IgE. It can also be used as cross-linking agent for allergen-independent triggering of mast cells and basophils.

Gene: IGHE, chromosome 14q32.33
Research Area Immunology, Secondary Antibodies
Application Notes For functional cellular assays (mast cell / basophil activation), when used at dilutions 1:100, the sodium azide free formulation is recommended Quality assurance: Reactivity > 99 %, compared to calibrator (Internal Standard mAb Le27), tested by ELISA binding to immobilized human Standard IgE (SUS-11)
Restrictions For Research Use only
Concentration 1 mg/mL
Buffer PBS, pH = 7.2, 0.1 % NaN3
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Monoclonal antibodies should not be stored at a temperature below -25 °C due to the aggregation effect of the protein.
Storage 4 °C
