Target Background
Rat IgG antibodies are classified to four subclasses mainly based on the isotype of the heavy chain (IgG1, IgG2a, IgG2b, and IgG2c for the heavy chain; kappa and lamda for the light chain), of which IgG2b and IgG2a, and kappa are the most abundantnamed in serum. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain.
