Anti-Human IgG(CH1 Fragment specific), AlpHcAbs® Goat antibody Alpaca Monoclonal

Function

Anti-Human IgG(CH1 Fragment specific), AlpHcAbs® Goat antibody is designed for detecting human IgG CH1 fragment specifically. Anti-Human IgG(CH1 Fragment specific), AlpHcAbs® Goat antibody is monovalent, recombinant single domain antibody fused to goat IgG Fc(mutation). Based on immunoelectrophoresis and/or ELISA, Anti-Human IgG(CH1 Fragment specific), AlpHcAbs® Goat antibody reacts with human IgG CH1 fragment selectively, no reactivity with rabbit, mouse, rat, goat IgG. 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. IgG is the most abundant antibody in normal human serum, accounting for 70-85% of the total immunoglobulin pool. Human IgG consists of four human subclasses (IgG1, IgG2, IgG3 and IgG4), and each contains a different heavy chain. The whole IgG molecule possesses both the Fc region and the Fab region, which possessing the epitope-recognition site. The IgG contains two heavy and light chains(kappa or lambda). The heavy chain is about 50 KD and the light chain is about 25 KD. The heavy chain chains consist of a variable domain, VH, and three constant domains CH1, CH2, and CH3. The common IgG is monomeric with a molecular weight of approximately 150 kD. Using antibody with Fc(mutation), the background from Fc receptors will be eliminated.
