Antibody Structure and Domains. Antibodies (IgM, IgD, IgG, IgA and IgE) are made up of 4 peptides—2 identical light chains (shown in yellow) and 2 identical heavy chains (shown in blue). The light chains are made up of 2 immunoglobulin (Ig) domains—1 variable (VL) domain and 1 constant (CL) domain. The heavy chains are made up of 4 or 5 Ig domains—1 variable (VH) domain and 3 or 4 constant (CH) domains.

IMMS EXAM? ------------------------ Can you tell what I'm revising today?? Complement system is activated by antibody:antigen complex, or mannose (or similar sugar which binds to MBL) or directly by microbes. These trigger classical, lectin or alternative pathways respectively. Tags? science immune immunology human body health defence healthcare medicine drugs hiv h1n1 infection disease cold flu
