Mouse IgG2c isotype control antibody

The mouse IgG2c antibody is produced in certain inbred strains such as C57BL/6, C57BL/10, SJL, and NOD, which does not express the mouse IgG2a antibody, and vice versa. If one uses any of the mouse strains for animal research, it is better to use the IgG2c antibodies rather than the IgG2a antibodies. There are more and more IgG antibody formats with Fc engineered. The format with the Fc silenced, Fc silent, or Fcs with silenced effector function is the most popular. Thus, the wild type mouse IgG2c isotype control and the Fc silenced mouse IgG2c isotype control mutants should be used in such an application.

Background

Mouse IgG antibodies are classified to four subclasses mainly based on the isotype of the heavy chain (IgG1, IgG2a or IgG2c, IgG2b, and IgG3 for the heavy chain; kappa and lamda for the light chain), of which IgG1 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.
