Information d'application

Indications d'application: For functional cellular assays (mast cell / basophil activation), when used at dilutions < 1:100, the sodium azide free formulation (Cat. No. 0911-1-005-B) is recommended

Restrictions: For Research Use only

Stockage

Concentration: 1 mg/mL

Buffer: PBS, pH=7.2, 0.1 % NaN3

Agent conservateur: Sodium azide

Précaution d'utilisation: 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.

Conseil sur la manipulation: Aliquot to Avoid repeated freezing and thawing.

Stock: 4 °C

Sujet: Recombinant human IgE to be used as reference for IgE concentration measurements in biological samples (ELISA, FACS). IgE (SUS-11) recognizes the human high affinity IgE receptor (FceRIa), the human low affinity IgE receptor (CD23) and does not interact with the corresponding IgE receptors of other species. It can be used as functional reagent in mast cell / basophil cellular assays, e.g. for controlled sensitization of such cells and subsequent cross-linking with either anti-human IgE mAbs mAb LE27 (Cat. No. 0908-1-100 or a specific recombinant cross-linking agent.
