Immunoglobulin Chains - 1
•ULight chains
•-has both constant and variable regions
•-two chains per each immunoglobulin molecule
•Leither 2 kappa (6) or 2 lambda (8) but not one of each
•-each light chain has an amino terminus and a carboxyl terminus
•UHeavy chains
•-has both constant and variable regions
•-heavy chains are structurally distinct for each immunoglobulin class
•-each immunoglobulin class or subclass is associated with characteristic biological functions
