Product Name :
Anti-Human IgA, AlpSdAbs® VHH
Applications:
ELISA,IP
Reactivity :
Human IgA
Conjugate:
Unconjugated
Advantages :
High lot-to-lot consistencyIncreased sensitivity and higher affinityAnimal-free production
Description:
| Description: Anti-Human IgA, AlpSdAbs® VHH is designed for detecting human IgA specifically. Anti-Human IgA, 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 IgA, AlpSdAbs® VHH reacts with human IgA selectively, no reactivity with human IgG, IgD, IgM, IgE. | Immunogen: Human IgA | 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 IgA | Cross-Reactivity: Does not bind to human IgG, IgD, IgM, IgE | 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. They are classed according to the heavy chain they contain – alpha, delta, epsilon, gamma or mu respectively. IgA is the major immunoglobulin class in body secretions. It may serve both to defend against local infection and to prevent access of foreign antigens to the general immunologic system. VHH are single-domain antibodies derived from the variable regions of heavy chain of Camelidae immunoglobulin. The size of VHH is extremely small(
