General description
Binds human IgE; does not bind human IgG, IgA or IgM.
Monoclonal Anti-Human IgE (mouse IgG2b isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Immunoglobulin E (IgE) antibodies are tetramers with two light chains (κ or λ) and two ε-heavy connected by numerous intrachain disulfide bonds. IgE exists in two isoforms, one is associated with the B cell receptor and the other being secreted by plasma cell. It has a short life span in plasma when compared to receptor bounded IgE.
Application
To confirm that a chimaeric monoclonal antibody had episolon chain, an elisa was performed using monoclonal anti-human IgE antibody (clone GE1) at a 1:1000 dilution.
Biochem/physiol Actions
Immunoglobulin E (IgE) is implicated in acute allergic reactions and chronic inflammatory allergic diseases, such as allergic asthma and chronic urticaria (CU). Receptor bounded IgE aids antigen uptake and modulates the differentiation and proliferation of B cells. It confers immunity against helminthic parasites. IgE is also involved in facilitating type I hypersensitivity reactions. It regulates mast cell homeostasis and also exhibits immunomodulatory effects.
Monoclonal Anti-Human IgE is immunospecific for human IgE. No cross-reactivity with human IgG, IgM or purified light chains is observed.
Physical form
The product is provided as ascites fluid with 0.1% sodium azide as a preservative.
Preparation Note
For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
Analysis Note
The antibody is tested for reactivity against myeloma IgE and allergy-elevated IgE.
