Description:
| Description: Anti-Human IgE, AlpSdAbs® VHH is designed for detecting human IgE specifically. Anti-Human IgE, AlpSdAbs® VHH is monovalent, recombinant single domain antibody derived from the variable regions of heavy chain of Alpaca pacous. Based on immunoelectrophoresis and/or ELISA, Anti-Human IgE, AlpSdAbs® VHH reacts with human IgE selectively, no reactivity with human IgG, IgA, IgM, IgD. | Immunogen: Human IgE | Host: Alpaca pacous | Isotype: VHH domain of alpaca IgG2b/2c | Conjugate: Unconjugated(6*his tag and one cys were added at the C terminal of the VHH) | Specificity: Human IgE | Cross-Reactivity: Does not bind to human IgG, IgA, IgM, IgD | Purity: Recombinant Expression and Affinity purified | Concentration: 1mg/ml | Formation: Liquid, 10mM PBS(pH 7.5), 0.05% sucrose, 0.1% trehalose, 0.01% proclin300 | Storage: Store at –20 °C(Avoid freeze / thaw cycles), Stable for 12 months at -20°C | Background:In mammals, antibodies are classified into five main classes or isotypes – IgA, IgD, IgE, IgG and IgM.{{2249435-90-1} medchemexpress|{2249435-90-1} Biological Activity|{2249435-90-1} Formula|{2249435-90-1} manufacturer} They are classed according to the heavy chain they contain – alpha, delta, epsilon, gamma or mu respectively. IgE is the class of antibodies produced in the lungs, skin, and mucous membranes. It may protect against parasite invasion, but it is a major factor in allergic reactions. The antigen-specific IgE interacts with mast cells and eosinophils, triggers the release of histamine, leukotrienes and other substances that lead to the itching, sneezing and congestion of allergies – and the life threatening respiratory distress of asthma and anaphylactic shock.{{1062368-24-4} MedChemExpress|{1062368-24-4} Purity & Documentation|{1062368-24-4} Description|{1062368-24-4} supplier} VHH are single-domain antibodies derived from the variable regions of heavy chain of Camelidae immunoglobulin. The size of VHH is extremely small(
