Animal-free production
Description:
Anti-Human IgA, AlpHcAbs® Goat antibody is designed for detecting human IgA specifically. Anti-Human IgA, AlpHcAbs® Goat antibody is monovalent, recombinant single domain antibody fused to goat IgG Fc(mutation). Based on immunoelectrophoresis and/or ELISA, Anti-Human IgA, AlpHcAbs® Goat antibody reacts with human IgA selectively, no reactivity with human IgG, IgD, IgM, IgE.

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.
Using antibody with Fc(mutation), the background from Fc receptors will be eliminated.

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
