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)

注意事项
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.
注意事项
Monoclonal antibodies should not be stored at a temperature below -25 °C due to the aggregation effect of the protein.

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.
