What Is the Immunoglobulin Heavy Chain?

The immunoglobulin heavy chain is also called H chain, heavy chain. A polypeptide chain in an immunoglobulin monomer. Each H chain consists of a variable region (VH) and a constant region (CH). According to the sequence of amino acid composition in the H chain constant region, Ig heavy chains can be divided into five types, namely (molecular weight 5 × 104), (molecular weight 5.5 × 104), (molecular weight 6.2 × 104), and ( Molecular weight 7 × 104) and (molecular weight 7 × 104) chains, in which the sugar content is about 4%, 10%, 18%, 15% and 18%, respectively.
